Anyone ever tried putting WRX or 300zx seats into these cars?

I'm contemplating swapping mine for something a lot more comfortable. Price and how easy they are to get are limiting factors for me. Plus they need to be foldable to allow access to the back seat. No electrics either...

I've seen people here in AUS put seats similar to the GTO seats you guys have. Look like these:
