cool fair enough
I've got to admit that i pondered a lot about adding steel floor pans i went-for due to their weight, so it'll be interesting to see what alternatives there are out there.
What about carbon fibre? I know that there are a number of DIY kits on the market nowadays and if you get it formed/re-enforced in the right places to accept the seats it would be very nice!
But then you'd want to do other bits in carbon fibre and i can't imagine that it'd be cheap
