Port BSP or go bare metal with PE?

We've been developing about 50% of our project on the TWR-K21F120M development board with MQX. With the product's board arriving (MK22FX512VLK12, K22, 120Mhz, 80-pin package), we are torn between taking the time to port the BSP to the new chip or port whatever HW-dependent code we have now to a bare-metal application and using PE to generate the hardware-dependent code. I'd say that the current code would take around a week to take from MQX to PE.


Could anyone estimate the kind of effort required to do the BSP port? Maybe suggest a different BSP to start of, rather than the TWR-K21F120M one?
