Not that I know of.

You can bind an unused key combination to 'math-insert \mathbb' or 'math-insert
\mathcal'. (See Help > Shortcuts if you do not know how to create your own
bindings. Do not include the quotes.) If you use the shortcut inside a mathed
insert with nothing selected, it will create an inset for the font but put the
cursor just to the right of the inset (so you'll need to move back one position
to type in the symbols). If you have something selected, the selected content
will be switched to the font and the cursor will be positioned just to the right
of the last selected character but still inside the font inset.
Usually, when I'm using either of those fonts, it is for a small number of
repeatedly written symbols. Rather than creating a shortcut for the font (and
then forgetting what it was), I create macros for the specific symbols at the
front of the document (so that, for instance, \sX expands to \mathcal{X}).
