One thing I'm considering is to just use the regular pumps to transfer
fuel. If you plumb the tanks to a fuel selector, then when you select
the aux side the excess flow will end up in what's now your primary
tank.

This is probably a step better than having one pump per tank.  The only negative I see is not being able to run the tank out without killing the engine.  With all the tanks you're talking about having, that's probably not a big deal, but the RV-3 only has two 15 gallon tanks, so using every last gallon is useful (if I ever went anywhere).

I've seen the 1st idea work in certified planes; the 2nd idea is wild
speculation.

Thanks, but I have enough wild speculation of my own :-)

(Wish you could have made it up here this weekend; if you get bored &
need a place to fly come on up for lunch sometime.)

Roger.  It might happen some day.
