I am wanting to take the cruise control out of my del sol SI and put it in my civic sedan. Will this be more of a pain than it is worth?

Also i got a spare lx 4dr that I am thinkin about swapin the doors to get power windows/mirros etc. Will this work? Will this be worth the effort? I might also be able to take cruise from this car instead but it has no engine so i dont know what all is there.
