They certainly wouldn't be original in any way to the cars - but if they fit the footwells and that's what you want, then go for it. Knowing how many sellers/makers of mats there are on eBay, I am sure you'll find what you want.
Bear in mind however that the footwells are ahaped very differently from side to side and RHD/LHD cars - so there are four mats.... RHD Passenger, RHD Driver, LHD passenger, LHD Driver
Be careful out there...
