If this is what you had in mind for the front MM bracket it is a pretty
good idea. We went around and around on this for a long time a few
years ago.

Main problem is they are not easily adjustable.  The Questair
Venture proves that is important. Higher top speed and better MPG if you
get the thrust angle right. Less trim drag.

I took my drawing and stripped out some things and got it close to your
latest drawing using the rubber rod-ends. Your drawing shows I can even
remove the three tubes marked with x's. Almost looks like too few tubes.

Looks good.
A lot fewer tubes so it should be quicker to weld with less distortion.
Makes a 1/4 scale model and use a 1/2 plywood firewall to simulate the torsional
stiffness you get from the full size fuselage. That is the secrete to 
these types of mounts. They exploit the torsional stiffness available
in the fuselage.

I would have Jerry weld it up because he has a good strong jig. A good strong jig is very
very important as I found that out the hard way when I had mine built.

Going to the top of the firewall will give a bit better angle. Don't forget
to order left and right hand ball joint threads so all you have to do is give the tube
a few twist to adjust the angle.
