Paul, nice drawing.
I'm considering the pan mount for our Cozy but like the idea of the Barry mounts closer to the engine, rather than on the firewall.
What if the pan mount were suitably thicker and then hogged out to lighten where appropriate, then have the Barry mounts in the material that protrudes from the sides.
But do this with one difference.. the ears that protrude and the mounts are at the powerplant & drive CG. This would shorten the tubular mount a few inches too.
Any merit to this idea?

It will work fine. Makes fitting things like exhaust manifolds a bit of 
a chore as the diagonals tend to go right through the exhaust
manifold and the water pump intake. Make  a 1/4 scale balsa model to
check clearances. Also there is the heat issue. The rubber will run
close to its 200 F limit on the exhaust side.

Be careful about hogging it out as the bending stress is a maximum right where
it goes between pan and block. That is where you need max thickness
of course.
