What do you guys think of the viability of a front cover cast into
the form
of a standard Lycoming dynafocal-1 mount?

The motor mounts on the 12A covers, crack the covers. When between cracking
the covers it is busy pulling the four threaded studs out of the cover. Hanging
the full engine weight on the already too thin front iron is out of the
question. Later engines are suspended from the center iron where they should have
been from day one.

Some method of adapting a plate at the oil pan face and a structure to get
some of the load to the rear plate or adapter would be fine. There are too few
bolts and those are too small for any bending load.

There are no disastrous shaking modes to null out with the rotary.

A design that leaves out the front iron as structure would work. It could
also add a mount for an external oil pump. An alternator pad and vacuum pump pad.

You can build a crank trigger setup and eliminate the angle sensor. They will
start and idle at full advance without protest.
