Rear seat mod idea : seat camber

[Grinnen]

I see a few people here have modified their rear seats to fold and what not which I started to look into, then I thought of another idea : 

 

Can the rear seat camber be changed so the whole seat tilts back a bit, for a little more bucket effect?

 

I've sat in the rear a few times and have always found the seat back too straight vertically, and the seat bottom too flat. Tilting the whole seat would make it a bit more comfortable feeling.

 

Anyone try this? I still need to figure how to remove the rear seats,I imagine a few well placed shims would do the trick.
