It might be possible?

Use an inverter and diode rectifirer of the resulting A/C or just run
on A/C.

One of our retired electrical engineers could probably come op with a
set of plans to build or how to modify a commercial Inverter
(12DC/110VAC) you can buy anyplace.

A basic question. How many homebuilts are IFR certified and are flown
in icing conditions and need a heated pitot tube?

No. A 28 volt pitot on a 14 volt system will only develop 1/4 of the
design wattage. I feel your pain; the price of pitot tubes these days is
absolutely, downright obscene.

Will running a 28 volt pitot tube heat on 12 volts heat it enough to use? I
keep seeing 28 volt pitot tubes on e-bay and was wondering if they would do the
job.
