New Method for Vocal Recording

yup.  i often follow this method.  to the tee

I'm with Lynn here, this is why it is useful to have some form of reverb earlier in the chain, whether it's a hardware one or an audio interface with built in fx.

Still, if you don't have that option, I understand the appeal of this workflow!

An alternative ...
Bounce the mix. Route the bounce to a direct out, not the master bus.
Goto console view and add pro channel power buttons to a group and the mute buttons to a group. Don't include the bounce.
Goto track view.
Click a mute button on a track to mute all.
Click a power button on a pro channel to disable all.

Reduce sample buffers.

Record vocals.

I certainly understand this workflow very well .Although I'm not a singer nor do I work much with singers . I use this type of workflow for other creative reasons .
I pretty much do the same exact thing when it comes to laying down all my lead guitar tracks and the occasional midi guitar synth parts .
I always like to have a parent project & a child project .
The child project  is wide open containing a mix of everything I plan on keeping for my song project / track .
Working this way the child project always seems much snappier for a few reasons .
All the plugs and sounds I plan on using for this premix / work-file were already rendered and my GUI is wide open .
Having a wide open GUI fits and works for my emotional temperament ...
Having to contend with clutter and distractions on my computer screen seems like a  good excuse for the Muse to go away and take a long vacation and never come back 
Since I don't want that to happen I bow down to her Mighty Holiness and stand there with a large palm leaf to fan her gently as I peel her lunch time Grapes if have to 
Baby please don't go , Baby please don't go, Baby please don't go down to New Orleans because I love you so
 
For SONAR to SONAR projects and playing transfers this works pretty good ..I may even decide to open up the Parent project and copy over my newly created performances over from the child project in one felled swoop. 
Ultimately everything including The Good The Bad and The Ugly will end up in my SONAR Parent project anyway .
 
I certainly want it all there
FWIW , I don't seem to mind all the pre work and planing that may be involved . I'm OK with that .
A small minor RUB can be keeping a very close eye on file management and keeping a tidy musical household ...
With SONAR to SONAR this is not such a big deal for me ...
 
Sometimes I use other brand DAW's that have all their instruments , plugs and other doodads locked strictly to them ...
For example , Logic has some real nice sounding synths and plugs , same with Samplitude and Abelton Live ..
When I want to accesses some of the synths or locked only to the brand of DAW sounds .
I don't consider it such a big deal to send my mix from my parent project over into some of these other DAW's to be able to work with and to be able to access sounds I cant access in SONAR only...
Now some people may feel this is a major waste of time ...personally I don't ....
The day I can afford the money to go out and buy every 3 rd party sound sample , synth library and plug that I can stuff into SONAR that I feel  will make me happy , That will be the day I will be able to keep all my work strictly SONAR ..
All these other DAW's export audio and I always bring my work back into SONAR anyway ...
Once again the only major RUB I have found is keeping my file management issues in check and keeping a clean concise track of where all my files and projects including the children are ...that in it self can be a lot of work ...
anyway that's my story and I'm sticking to it
all the best,

All you need to do is do the mix down to a stereo track in your project and then toggle the FX.  

Absolutely. 
 
OP seems to be trying to invent the square wheel here.

It's also a good idea to temporarily Archive all the tracks that you don't want to hear while recording. All audio and midi data associated with these tracks will then be ignored by the audio engine.

I use the monitor system in my RME audio card to mix the live audio back into the headphones..no latency.
 
Before that I would use a mixer that would send one track into the audio card and split another into a mix.  If you mix the vocal track back into the mixer at a lower level you can put reverb on it and the vocalist will hear the vocal with a little delay and verb on it.
