Check in with the people at GAOwnersClub.com - the Grand Am uses both of those V6's and they sometimes swap parts. I would think that the engines can be swapped along with the ECU but there may be modifications that I'm not aware of.

throw in a 3.8

I'd go with a 3800, get a newer L26 out of the junkyard from an 06 or newer Lucerne, Grand Prix, Lacrosse, etc. Can be had very low mileage for cheap price. Slap a new intake on with your old throttle body and it'll be bullet proof for another 300k miles.
