Therefore versus fiberglass the aluminum surfaces
will cool to icing temperatures faster, and conversely will heat to
non-icing temperatures faster.

Yes, exactly.

The composite will cool more slowly,
but once cooled, will retain that temperature much longer, meaning like
I discovered this morning, my composite plane will/may be iced when the
Cessnas, Pipers and Mooneys won't.

Consider also, the mass of composite v aluminum necessary to achieve
the same strength. I'd guess the composite skin thickness exceeds
that of the aluminum skin.
