Default 05 wrx 2.0 conv. to 06 wrx 2.5 Questions???

I blew my motor in my 05 WRX and i got a really good deal on a 2.5 out of an 06 WRX. I believe i can just change my wiring harness and ecu to 06 and go to my local dealer to get my key flashed to the new ecu. Is this in anyway correct? I already have my motor out and the 2.5 is ready to be dropped in.

The only thing i can think of not workin is my tranny not workin togther right.
Im no subie tunner but i learn really fast so your comments are very helpful.
Thank you for your comments

Does anyone know if i can just switch out my intake manifolds and harness? Then get my ecu reflashed for the 2.5 block and just bypass the AVCS? If so, how do u bypass AVCS? I read it could be done at http://www.gruppe-s.com/Clearance/FXT.htm
