I think so. Microchip have done a modified version of GCC-3.3 with DSPICs support, so we have got a heavy good base to work on the instruction set, wich is similar for PIC18. DSPIC is a 16 bit CPU, so is memory isn't segmented.
Just as a reminder, even though the Microchip code is covered by the GPL, code based on it won't be acceptable for inclusion into FSF GCC unless you can get Microchip to sign a copyright assignment, which seems unlikely. Any code in FSF GCC needs to be written by someone with a copyright assignment to FSF, or at least a public domain release. (I'm not sure on the exact rules here. Someone at the FSF would know exactly.)
