Need thoughts on custom seats...

I was wondering if anyone thinks if its possible to fiberglass a seat? If not, I was thinking of making some fiberglass car seats, of course they would probably be a set fitment instead of reclining for starters. I was planning to making the frame and then finding some nice cusions/pads to use for the back rest and seat. Then finish the fiberglassing and bolt in the cusions. Does anyone think this would be neat/feasible, or just a waste of time/money? Plan on pretty much fiberglassing the whole interior of the car I remind you, nothing too "crazy" more of a sleak look is all.
