Interesting idea.

Would you trust it?


Maybe, on two provisos:

1) It is screwed to the joists below to prevent lateral slippage

2) The false floor on top goes "wall to wall" to prevent shear of the whole
structure.

The reason for that conslusion is it is approximately the same structure as
a computer room false floor and they are OK unless you take out a big square
and leave a small island dangling in the middle
