Of course, and it has been done, but most of the time the molecular
people just use similarity as a criterion for relatedness.

I think that sequence information should only  be used if nothing else
works. If you can't identify any reliable morphological traits try
sequencing a couple of genes with broad outgroups. What to sequence is
hard to decide. Go for something linked to morphology or metabolism.
