That should work fine. When I was climbing in the TreeMotion I used the same setup as Richard, with the CT roll n lock, for awhile. Though it worked well I found that I just didn't use it very often, so when I switched to the MCRS I left it off.
I have heard concerns that having a rope grab in that location could conceivably damage the rope sheath if it were shock loaded. Doesn't seem likely but something to think about I guess.
