Usually if you wish to operate both DPL and PL on the same channel you decide in advance NOT to use 131.8Hz for anything.
I remember a salesman's radio that was set up with PL encode/decode and a multi-DPL encoder for multiple community repeater access; of course that was back in the days when the standard user radio was a Mitreck. I don't think that I would want to try it with a synthesized radio. Most likely the VCO would try to track out the DPL signal, crystal controlled radios didn't have that problem.
