I think one should use the information one has available. Any
discrepancies found could be interesting.

Hmm... Sequence data that is directly linked to morphology?
I don't think that is much of an option at present given the
uncertainty in mapping the genotype to the phenotype or gross
morphology. As Ed Rybicki said, this is also not a lot of help
for bacteria (ie. most of the organisms on the planet) or viruses.
Metabolic or structural genes seem a better bet and that is part
of the reason why they have been used.
