This could be problematic.  All the spirit levels that I know of are
based on gravity pulling a liquid down and the buoyant bubble rising to
the high point of the curved container.  They don't work upside down!

You would need to mount a level that can be viewed through its
underside, such that it is inverted when the camera is right-side-up and
right-side-up when the camera is inverted.  Circular levels definitely
are out.  A curved-tube type spirit level would work, provided it were
mounted in something transparent, like plastic.  I recall seeing a
spirit level in a block of lexan, but I can't recall where...
