The official statement is that it is neither possible nor supported. It was even highly marketed as separation in the earlier days.
But i have seen a couple of occurrences (including a network crippling looping and therefore amplification of traffic e.g. back in the M5i days) where some traffic leaked from fxp0 to data plane and/or vice versa.

Even if it would work you would not want it as the CP/DP link is pretty "slow" and already tasked with lots of other things which it struggles with at times ;)
