Aaannnnd....comment!

I mean, I like the idea. Sounds like a leaky nightmare, but I like the thought.

Not really, about 36 lbs slightly aft and the same slightly forward

Now that I think about it, you could make tubes that slide in from the wingtip and fit in the cutouts in the ribs. If you did it before the wings were covered, you drill a hole in the outboard end of the wing tanks, install a connecting tube with a check valve so fuel only runs inboard from the tubes.

Then again, I forgot about the drag/anti-drag tubes...

External wing tanks that attach to strut brackets and have electric pumps

Wing tip tanks that are profiled to wing shape, and could attach by telescoping tubing that extends into spars (they would “plug-in” to the end of the wing)

Belly pod with electric pump


I’ll admit, the wet spar was sarcasm, but now I am seriously considering some of the other options...
