yeah i dont think it would be worth the work to put them in, but if you dont have a crx seat at all and this is the only other seat you have, i guess you really dont have much to choose from

but to do a pan swap you're going to have to remove the pan(basically the whole underside of the seat, including the sliders and everything) from the underside of the seats, and put the crx pan onto the civic seat. Just look it up on google or h-t im sure there's something somewhere about pan swaps
