I would say so, not having seen your config etc. Suggest getting with your 
local account team to analyze that.

In terms of OSPF, BGP, & NAT, we can do all those. We do have h/w 
accelerated NAT in sup720 for TCP & UDP traffic.

Sure, you can do that.

I assume you are meaning you want to use existing PAs from the 72/7500 in a 
flexwan carrier card in the 6500? I am not too familiar w/all the WAN 
options for 6500, do note that some PAs are not supported.

If you mean will sup720 hardware CEF (FIB/ADJ) work with flexwan, the 
answer is yes.
