I am no expert, so take anything I say with a large grain of salt, but saving each take as a seperate project seems like the PITA. Takes in Reaper are pretty easy to deal with once you get used to working with them. Record your first take, set the cursor back to the start point, record your next take, and so on. Above each track it will show which take you are on (take 3/5, e.g.). To toggle between takes of selected tracks, hit "T" ( I think, not in front of reaper atm). Easy to comp takes too - for example use take 3 for the intro, take 1 for the 1st verse, take 4 for the chorus, etc. this explains it much better than I ever could (if you haven't already, watch all of Kenny Gioia's tutorials accessible from the reaper home page, they are excellent):

You should be able to sit at your drums and record ten takes in a row without getting off your rear-end using TouchOSC doing it that way. I don't think it's possible to open/close projects, insert track templates and such with TouchOSC (again I am no expert). AFAIK, you can only adjust levels, pan, fx sends, use transport controls, arm tracks for recording, solo/mute, and probably a few other mixer-related functions that I'm forgetting.
