I believe not, as the code for this would require very low
level programming and StataCorp have yet to publicise how
to extend the graphics in this respect -- and on my guess
are unlikely to do that in any foreseeable future.
You can
1 use printable characters within marker label variables
2 -separate- into classes and use e.g. different colours
or grayscales
and
3 experiment with overstriking existing symbols.
I think those are the only alternatives.
1 and 2 feature in a Stata Journal tip forthcoming in SJ 5(4).
The experiments I have seen on 3 were not encouraging,
but this revolves partly on matters of taste.
