I'm thinking that re recording is the best way to do it. I just hate losing these takes because they sound incredible. The main reason I need to lock to grid is because of midi. Midi is perfect and I need the drummer to be perfect as well. :) Tall task!
 

Here's a thought - Keep the great drums as they are, and build a MIDI tempo map to match the drums?

What Slugbaby said.
Use "Set Measure Beat at Now" to put the grid where the drums are instead of moving the drums.

I agree with Slug and Base, if it sounds good and you would like the hits to line up with the time line adjust the tempo map instead of  messing with the audio. If you need to move hits I agree with Sylvan, Chopping up the clips instead of time stretching sounds better. Whatever you do to close mics needs to be done with the overheads as well otherwise you will be messing with timing/phase. Here's what I do if I have to quantize drums:
 
It’s important that all the edits and cuts happen at the exact same place on each of the multi-tracked drum tracks to maintain phase coherency.
Make sure they all have the same transient markers. It’s better to chop them up and move the slices around.
Disable the transient markers on the overheads (right click select all -> right click over a marker and disable). Work with the close mic sounds as the source for establishing transients.
Select all the drum tracks. Right click on any track, choose merge and lock markers. Little yellow locks will show up on the clips. All the transient markers from all the drum tracks are copied to each drum track. All the drums share identical transient markers.
The next step is to unlock the clips. Switch back to clip view on all the drum tracks (control + shift + click and select clip). Right click in the background select clip lock and uncheck lock position.
 Switch back to audio transient view. The yellow locks should be off.
Call up the Audiosnap palette and select split beats to clips. Now that the clips are split you can use the quantize process. Process -> Quantize -> select a note value (1/8^th) under resolution and audio clip start times under change. Leave auto Xfade times and fill gap checked ( 20ms and 80ms). Click OK.

Cool, I prefer that to my previous workflow, thanks!

overheads bleed and phase issues are always a concern, however in my travels, I have found when slicing / moving kicks, snares or toms slightly.. Once the kick, snare or toms is gated and compressed, you will never even hear the minimal difference through the overheads. But , that's slight movements.
With all this being said, your probably better off lining the grid up to the drummers performance

If you wanted to invest in the upgrade to Melodyne 4 Editor....
I record 12 tracks of live drums with Sonar, Import them into the stand alone version of Melodyne.
It detects tempo better than anything that I've personally tried
From there, you can change to a constant tempo.
I've never experienced any phasing issues
I've actually been able to adjust tempo by several BPM without it being noticeable
 
Then, open a new Sonar project, set it to the proper tempo from Melodyne and import the files.
All your drums are in time and in line with the grid.

Awesome, I need to take this for a spin. Thanks
