Yes, it can be done, but it's far more flexible to use Direct Digital Synthesis to generate arbitrary frequencies over a very wide range. Here is the description of a Frequency Synthesizer that we recently built 250 copies of. Very popular in our lab and with FAEs. We are looking at the next generation going to a few GHz using MGT outputs. Fun project...
