maybe not
my two trafos weighs in at about 10kilo, each
and they are only 2x38V (2KVA)
so if you want twice that voltage...
my usual layout preparation exercise 
anyway...if I really is going to do this, I have decided for a pro style 19" rack box, with heatsink both sides (300 x 165mm)
to get enough heatsink surface I will use one side for NPN output, and other side for PNP
input/VAS will be placed on a long board connecting the two sides
input in the middle, and VAS closer to driver/output

I'm still working on the 2U high version...Mile is just joking, eh! Do you want to lift up your amp with a forklift?
Edit:
Sajti
Just playing around with the shematic....
Its not easy....
I suggest drivers and VAS transistors on main heatsink with outputs...
thanks for checking
component numbers help 'orientation' and spotting errors
hope its better now

Very artistic approach
¸Another suggestion
That's much better. Those thin copper tracks wouldn't withstand high current flow. At least 400mil wide track or polygon should be placed, like Apex showed.
