I'm reasonably sure that would not have been possible, as they were close
to the limit of (air resistance/engine thrust = maximum speed) and (range
= (available fuel)/(cargo weight & space in the aircraft)).

The computations certainly lead to a desire for much more energetic
fuels and engines capable of handling them.

What proportion of the SR71 is fuel tankage?

About 110%, judging by the published -1 manual.

This is a rather unfair comparison, the SR22 flies around twice as fast
and rather higher than Concorde. A more reasonable comparison would be
the B1B.
