I recall Tim Suddard at Grassroots Motorsports had a one piece 
fiberglass (?) spring made for the Spitfire project he was working on.  
Don't know if that idea ever went anywhere.

I have seen many different types of rear race springs over the years some had less “Leaf’s” some more. (Than stock). I also have a “trick” one that is all one piece made of some kind of composite material that is a fraction of the weight of the typical leaf type, but I have never tried it. 
So at one time such a part was manufactured. 
The ones I have had in race use were custom made long ago and lasted forever.  
Me thinks your best bet would be to test the spring rate of your current one and see if You can have a niche expert add a leaf or redesign, remake, make stiffer.... similar stuff is still used in trucks and trailers etc. 
Playing with the distance between the two hole ends has also been talked about as way to modify camber. 
Happy to share any measurements or specific info about the various ones I have if needed. 
Keep us posted.
