2005 XC90 T6 2.9 AWD

I was wondering if I could swap my 2.9 to a 2.5 AWD if I had both the motor and transmission from the 2.5.

Any idea? Any problems I might come across?

Thank you for any help!

No, not easily anyway.

Problems would be cooling system, intercooler, ECM, TCM, CEM, pretty much every other module
