Simple is always good.
I'd look at having a fully isolated solution. Get a small isolated DC-DC (1-5W) plus a modern signal isolator and drive 8 gate drivers with that.
Specifically I'd look at using 2 isolated supplies (NXJ2S1212MC, though 2W may not be enough), one for high side and one for low side plus an SiLabs isolated half bridge driver (Si823X). Then re-buffer the output of the SiLabs with 8 of these (ZXGD3005E6).
