Only thing I see is you will have to have 2 Envoys. The IQ inverters send
the data on the powered conductors, not on the neutral like the M250¹s.

Subject:  [RE-wrenches] Enphase IQ combiner for M series microinverters

Does anyone see anything wrong with using an Enphase IQ combiner to combine
two strings of IQ microinverters with two strings of M250 microinverters? I
would not use the production CT (just use microinverter production data).

I can't see any technical reason this can't be done. Do any listing or code
reasons come to mind?
