No, you can't flash it to ZHP tune, that's only available for MS45.
With a project this big I would consider converting the car completely to MS45. As far as I know it just requires your other computers (LCM, EWS) to be reflashed.
But you would obviously need all the b30 goodies - DME, intake, MAF, harness ...
