20D in a Subal C10 housing?

I have a 10d and subal C10 housing...

Was wondering if a 20d will fit inside the C10 housing and if, with some adjustment, the housing can be made to work with the 20d. I hope that I don't need to find out any time soon, but wondering about the life span of my housing given that a new 10d may be hard to come by fairly soon should I need a replacement.

what do you guys think?

Bill,

Won't work, the 20D's pop-up flash protrudes too far and hits the circuit board on the C10.

I was hoping for that too but no cigar.
