Perhaps consider the MCHP PIC24F family. There are parts there which 
have built-in USB (with OTG capability!) and the core processor 
architecture is identical to the dsPIC (sans DSP stuff). Then you'd only 
be learning 1 new processor architecture and the development environment 
would be the same for both parts.

For example:
