Only thing I really think is easy to take from VC over to FE is that characters don't die immediately, but instead can be saved before a certain number of turns. I found the instant deaths in FE Wii extremely annoying and are the reason I haven't beaten the game.
Other than that, it's a completely different game style since VC uses guns and FE uses mostly melee weapons. YOu can't really just supplant the VC style of gameplay into an FE world.
Also I think any SRPG should take a good look at the book presentation of VC, love that idea.
