When the alternative fuel discussion, and the automotive fuel STC, first
gained popularity; I read that 100LL AvGas was about 96 octane without the
lead.

That would suggest an obvoius solution of 96 octane for most of the fleet,
and blend-at-the-pump (or from the truck) for those that actually make use
of the higher octane fuel. OTOH, that makes too much sense...

Not economically. Not with the EPA around.
