It should work. The depth of a T=>4/3 should be the same as the combined
depth of the two adapters, shouldn't it?
The length of an OM=>4/3 adapter is always the same*, the difference in
register distance of the two mounts. If T-mounts had only been made for
odd things like telescopes and slide copiers, I could see where a
T-mount adapters could be of different depths, but they were originally
developed by independent lens makers to adapt their lenses to various
proprietary camera mounts. So as I understand it, each one is the
appropriate length for the register distance of the mount for which it
is made.
So, for example, the old Hanimex T mount WA my dad had focuses properly
to infinity with the T=>Nikon mount he had and also is at the proper
register distance on an OM body with the, different length, T=>OM mount
adapter I bought to attach OM bodies to a Meade telescope.

* Yes, I am aware of the small difference reported between the original,
free, OM=>4/3 adapters and the later MA-1.
