I'm not sure why these high IS players are your golden boys to run something other than LI...seems odd to me.
JR is needed for motion. besides which, if your plan is to run motion, I'll just play 3-2 and you will lose (assuming TSPs of players around same levels)...badly.... unless you play an LI or LP...which only shows how overpowered it is.
In BB you play a 2-3 zone and suddenly every guard becomes a Steve Nash / Reggie Miller hybrid.
