Have you ever cut one in half?

Certainly, many times I've cut larger ones down for smaller openings or
made a Dutch door out of a full-length one. Why, do you ask?

It wouldn't be difficult to work out a mounting as well; a moly from the
bottom or a tee-nut in an inserted block or similar would work just fine
since any access on the latter would be covered by the proposed surface
sheet anyway.

Utter nonsense. The door will simply crush or the fasteners ('t'-
nuts) will pull right through. Hollow core doors are fairly strong
over a large area but *not* over a small area (where there is no
support).

Not if you place the fastener through the bottom ply or add a local
blocking or a sleeve. As noted, (read next sentence again )it seems
like more effort than what could be gained but don't see any reason it
couldn't be done...

It seems like more hassle than gained, and the thickness could be an
issue depending ...

Of all problems with this (stupid) idea, why would the thickness
matter? RASs can usually be cranked up much higher than the blade
(minus motor) depth anyway. A solid-core door might work, but a
hollow-core door is an idea doomed to fail.

As noted, would mostly depend on the arrangement for the fence mounting
not the table itself. Generally w/ smaller saws of the
DeWalt/B&D/Craftsman ilk which one would presume is what OP has the
fence mounting is simply a couple of thumbscrews that are at height of
the thickness of a 3/4" table. W/ the thicker table, that would tend to
be too low and let the fence lean more easily since would need wider
fence to gain the desired height above table surface. The actual
thickness itself wouldn't make much, if any difference, on the column
height, no...


... Neither can be warped to
adjust for flatness, though. MDF is still the best solution.

Oh, I'm sure I could come up w/ something there as well...

I'd still recommend as before it would be simpler to use ply or MDF or
similar, but certainly can see the OP's thinking of it. W/ the
sacrificial top, as long as don't go thru that, the hollowness would be
totally immaterial.
