can i use iso120/121/124 i following application

I want to control the generation of high voltages i.e; around 5000V in dc/dc converters using transformer by controlling the duty cycle of switch in primary circuit through PWM regulator.As high voltage PWM IC's are not avaliable can i use above mentioned isolation amplifiers for sensing the output and can i give output of isolation amplifier to PWM IC by controlling the gain of isolation amplifier
