Reamping is certainly the ticket for sure . I've done it a few times at the last apt I called home .
The new place where I'm at now ...no can do ...
Yeah got the right amps , 66 Fender Vibroluxe Reverb, Old Marshall and some other assorted tube amps of various vintages and pedigree ..
In a small untreated space like where I'm currently at I suppose I would have to build a portable Isolation box just to do it right ...
As far as amp sims go they are basically a form of reamping inside the box .
Once the amp sims are not engaged you still have the original dry guitar signal unless you exported your guitar track and brought it back into SONAR as a rendered track with your guitars signal chain embedded ....
Even then , if one was smart they would have kept the original dry track they used for the amp sim

I have often wondered what would happen if I ever scraped up enough coin to rent a Properly Equipped Recording Studio with a large selections of mics . I would love to bring in tracking sessions I have done at home into a studio while having the luxury of using my own amps .....
