Under Floor Ventilation
I'm looking to improve the ventilation to a suspended timber floor with
some new vents - they'll open to an outside path that has built up over
the years to near internal floor level.
I see there's these 'periscope' type things:

But it seems to me they'd take a fair chunk out of the 9" solid brick
walls, and the air flow doesn't look that good.
Would flat letterbox-sized grilles over a say 10" deep 'pit' feeding a
horizontal cut through the wall below the existing floor work?
I can see the issue of debris falling in, but if the grilles are
reasonably removable I can't see that being a dire problem. If it is
doable, is there a source of grille/conduit - can't seem to see anything
online.
