"Solid" rear floor

Just wondering if anyone has replaced the ribs and ali floor of the rear tub
with a big piece of steel / chequer plate that attaches directly to the
chassis.
Could it be done and is it as simple as it sounds?
Thanks,
Jon SIII x 2 (both in bits)

If you use solid steel sufficiently thick to support itself on the chassis
pads provided without reinforcing (my guess is that you would need 6mm,
possibly 8mm for rigidity) - there goes most of your payload, especially
since the ends will be unsupported. And you would still have to attach the
floor somehow to the sides, front bulkhead and rear sill somehow or they
would rattle, not to mention the need to get some sort of seal between the
alloy and the steel. Thick aluminium might be more practical, if a lot more
expensive.

Ah! So not as simple as it sounds.....

Plus the body flexes sperately to the chassis so some interesting
stresses would be built up.
