And swapping computers might in turn lead to additional Aveo parts being mismatched with the new computer(s). So unless it's already been successfully done before, I don't think you can count on no mods being needed.
If this engine really is plug-and-play with no mods, then it would seem like just a matter of the price. But if you can't find anyone having done this before, you could be in for a project complete with lots of trial-and-error, and maybe spend quite a bit more than you planned to. If you're up for that, then fire away. You could also go with a boneyard engine, which is also fine if you don't have a problem with rolling the dice.
OTOH, if all you're looking for is to get it back on the road with the mininum amount of risk, and want the best chance of keeping it going as long as possible, buy a rebuilt 2007 engine that comes with a warranty. That would be more $$ up front, but IMO will be the best chance for the most trouble-free miles going forward.
