Mark,
Nice try but no cigar. Most aerobatic purpose aeroplanes have a
relatively small fuel tank located near the axis of rotation for
aerobatic purposes. They also have other tanks which are only used to
move about the country, not practice or compete.
A 300 series Lancair with a header that holds 9-11 gallons will not affect
the spar loading since the original design has the engine fed from the
header. Having an unnecessary 35 gallons in the wing does add to the
load and for what purpose. A smaller amount can't be reliably pumped into
the header during maneuvers that unport the wing pickup.

On
the other hand, weight in the fuselage, as opposed to the wing itself, puts
more stress on the spar. Life is full of little trade
offs…

On
behalf of those 300 series pilots that perform aerobatics, going out to
compete or practice with only a full header is prudent as fuel in the wings
may upset the balance of some maneuvers.
