How about something like this.

Tony Long EZ

These ears are known as cantilever beams.
If you make it thick enough (at least 3/4 of an inch) it will
be too heavy and still not as strong as a 2 inch high Schertz beam.
Also it will be very expensive to make as a chunk of aluminum
24 inches wide buy 24 inches long by 3/4 thick (43 pounds)
will cost about $200. I am assuming the ears stick
out six inches on each side of the oil pan. You could make it
in bits and pieces but unless you are a good tig welder it would
cost you more in welding labor.

On the the other hand you could do something like this
(last jpg) out of thinner material. There are still some
necessary gussets missing in these 3D's. These types of
combination oil pan and Schertz beams are complicated
and expensive to weld.

The draw back is engine oil heat is directly applied to the rubber
motor mount bushings. These bushings could be made from 500 degree
F silicone rubber and I think Barry Controls still sells silicone
versions of the motor mount rubbers at extra cost. Regular rubber
is limited to 200 F. Also the motor mounts come
out too close to the exhaust compared to a longer Schertz
beam and tend to melt for that reason.

Here is a wonderful and quick beam calculator.

The Schertz beam is in the category of a simply supported
beam.
