REFLECTOR:A (re)volting problem

Looking for any ideas out there.  My Velo has a 12v system but a 24v pitot,
which was installed prior to my involvement.  Is there any way of jumping
from 12v to 24v to drive the pitot, which draws a few amps.  The reverse,
24v to 12v, seems to be able to be done quite easily.  But going from 21v to
24v seem problematic and I haven't discovered any great solutions.

A second avenue of exploration is this Velo is equipped with two (2), 12v
batteries.  Is there a way of taking the 24v from the two batteries without
having a totally jerry-rigged system whose failure could potentially make
both batteries inop?  The dual battery, even though I've never had to switch
to the second unit, is a degree of redundancy that I would not like to
compromise.

Why not change out the pitot?  Well, the previous one was plated and fitted
for the plane, right on the pointy end of the plane and I kind of like it.
Changing it out with a 12v unit would be a last resort.  Ideas?
