I do not think that you will succeed to have something which
works by using this method. fvwm cannot do what you ask,
maybe in the future.

Xrender does not allows to make window transparent. This is
a legend (which comes from a screenshot). Xrender can be
used to apply 2 images in one via an alpha channel (an
obvious example is tinting). You can do that without Xrender,
but with Xrender you may hope that the operation is faster
(e.g., hardware acceleration).
