E21 316: E30 Sports Seats vs. Re-covering the Recaros

Saw these absolutely divine Recaro sports-seats from an early E30 Baur cabriolet on eBay. They're all but identical to the Recaro/sports-seats from the E21, but have different subframes for the E30, not that it would make any difference now I've started cutting out the stock mounts and the inner side of the E30 base fits perfectly to the inner-mount anyway, so would be a bit neater/stronger than my all-custom base. Only snag is, the price is a little more than I'm willing to pay as the rear seat and door-cards are included. I've got them down a bit, but I'm sticking to my upper limit and they're having none of it. 

It got me thinking, the shape isn't too different from the RS Turbo Recaros I have, it's just the colourful Ford fabric that doesn't suit, but there may be a way to create some ultra-cheap 'replicas'. I figure the stock E21 seats aren't worth much at all, so there may be enough decent fabric left on the two to re-cover the centre-sections of the Recaros in beige cloth. This leaves the bolsters/head-rest grey alcantara, which is where fabric spray-paint comes in, about a tenner a can off eBay, to make them dark-brown. I whipped the cover off one of my E21 seat to weigh it up and it does look possible. On the other hand it has the potential to mess up a great pair of Recaros that are worth quite a lot more still than I previously thought, as well as condemn a tatty but useable pair of E21 comfort-seats, which I could at the very least donate to someone. At the risk of the end product looking naff, I don't think it's worth the sacrifice.

** UPDATE - Another pair came up on eBay yesterday and guess what, the guy emailed back about the original set accepting my offer. The second pair are a bit dirtier and the back seat is wrecked, but the seller will come to about half the other offer, only thing is he wants collection and they're in Cardiff. It will cost me the difference to drive down there, plus a day spent sat in the car. To be worthwhile I'd have to get this second set for buttons, so I called up the original guy and bought the set above - they'll come Monday and I can use the rear bench. I'm glad this seat problem is finally put to bed as the MOT is a week on Saturday and I need perma-fixed seats!
