Boost converter controller design help.

I have designed a lead lag comoensator for a full bridge dc dc boost converter. The switching frequency is 100Khz, Vin = 60V Vo = 600V (1Kw).
I know that variables such as phase margin and bandwidth can be related to time constants such as overshoot etc.
I have designed this system for an crossover frequency of 1/10th of the switching frequency and (10Khz) and PM of 50 degrees.
Is 10KHz too high a crossover frequency(should I slow the system down considering the effect of the right plane zero?)? If so, what would be an acceptable value?
The bode plot, step response and system block diagrams are attached.
