That could be refused by software.
However, 20G cards should have also 10G backplane interfaces.. just 
marketing I suppose.

But, what you can do is to buy just SE600 or SE1200 chassis and move all 
cards (including XCRP3/4) to new chassis.
This will be the cheapest way to use 4x10G cards I suppose.
