Output regulation is possible using BCM PFC chip?

Hello,
We have done a simulation of a 15W flyback PFC in BCM using LT3799. (vout = 40V)

The LT3799 is supposed to feature primary side regulation, however, we have added a secondary side error amplifier, and an opto in order that the secondary side voltage can be regulated to 40V. (as in the attached diagram)

Is this OK?
Can the LT3799 be operated like this?.....it does seem to work ok on the simulator (LTspice)

by the way, also attached is the LTspice simulation

LT3799 Datasheet:
