I dunno man, I am not a hardware engineer...
So maybe the number of E cores can come down, but anything that has Pro somewhere after Mac needs a bunch of P cores & a whole bunch of GPU cores...
How about if we go with the following:
32 P cores / 4 E cores / 48 GPU cores / 16GB HBM2e UMA
48 P cores / 6 E cores / 64 GPU cores / 24GB HBM2e UMA
64 P cores / 8 E cores / 80 GPU cores / 32GB HBM2e UMA
