If there's enough DNA for a DNA sketch, then there pretty much has to be enough DNA for a regular DNA test. Nobody is going to go to jail for looking like a DNA sketch. There is a risk here where innocent people with no connection at all to the crime might be compelled to give a DNA sample. If the DNA from the "suspect" is tested, excluded, and then all information about that DNA is then destroyed, maybe that's not a big deal. But I don't think we have that guarantee now for DNA samples.
