Yes, please consider it. I would be very interested in the results.
We measured under 2 ps jitter for the PIC dividers  used with the cute little TADD-2 board . One of these days I should measure your divider board with the same setup to see how it compares with a PIC. Like a CPLD/FPGA the PIC has the advantage of being fully synchronous and all on one die.
