Looks a lot like what I did for the Dyke Delta I built if you leave off the yellow tube on both sides.  The nose wanted to droop down.  I even had two more triangle that attached to the top rear corners of the engine with adapters that I built.  The engine pivoted on the bottom rear supports.  The bottom front pushed up, and the top rear pulled back.

Well I think I have designed my mount for the Glasair.  Overall I think it will be a bit overkill but I am ok with that.

Should put the CG close to the same spot as for the Lyco.  Thrust point in the same spot.  Green bars were part of the Glasair mount for a Lycoming. (There was also one between the two upper points but I don’t think any of them are truly necessary with the stabilization of the plate.  Yellow bar I am calling optional at this point to make it easier to work with intake/exhaust.  Another idea we had was to weld on a flange for both sides of the yellow bar and have it bolt on during final install.

Thoughts?
