You mean something like this?

Yes it can be done, mine is still a work in progress. I got a bowrider mainly because my wife was okay with it. I plan on adding a rear casting platform and under floor rod storage this winter. I fabricated the trolling motor mount myself out of plywood, expanding foam, and fiberglass resin. It still isn't officially complete, I just blasted some paint on it this spring because it was time to fish, I plan to make it look a little nicer.
