The belts aren't the main problem, it's the seat mounts. The front and rear mount completely differnetly, and trying to mount a front seat in the back is unsafe for anyone who is not a professional. The reason I brought up legalities is that while the seats may pass inspection, in an accident, a poorly designed mounting bracket will not hold up to the stresses of the accident and break off. Seats and belts are an incredibly important piece of safety gear. Let's put it this way: would you mount your brakes with a piece of aluminum foil? No. Because YOU modified the seat in YOUR car, YOU are held responsible for the well being of YOUR passengers. It can be done, but it will take a lot of work and be pretty expensive. I do think it would look cool, but it's not worth the risk.

What might work better is the rear seat from an EG Civic Si. They were basically buckets but have to mount into the bench seat bracket. They might just fit into an Accord like yours. You can modify the seat a little to fit your brackets, which would be a lot safer than trying to modify the bracket to fit the seat. Find someone who's stripping their Si and swipe their seats and see if they fit.
