Default 2001 3.5 Liter swap into Chrysler 300 from a 2.7 Liter

I have a Chrysler 300 with a blown 2.7 and I have a 2001 Chrysler Concorde with a 3.5 with all kinds of body issues. I would like to swap out the 2.7 Liter with my 3.5 Liter, but there seems to be some unknowns.

I do know the mounts will have to be changed, I do know that I need to use the engine wiring harness from the Concorde, but what I can figure out is if I need to replace the pcm and if I am missing anything else?

Any help would be greatly appreciated.

Pretty sure this is a no go.
99-01 Electronics were the same. (can swap a few parts to make it work in 02-04)
02-04 Next Generation (can swap a few parts to make it work in 99-01)
(Flywheel/ Cam gear and more)
Above were considered "LH" series cars.
05 and up Chrysler went to yet another style of electronics making the older generation engines/electronics not compatible with the "LX" series cars such as your 300
