Anyone using mixed spectrum CMH/HPS?

I’ve been flowering with CMH for a little while now, mostly with the 630de units although I also have a couple 315 units that I move between veg and flower. Overall I’m happy with them, particularly the quality that they seem to provide. I’m looking at extending my flower table from 8x4 to 12x4 on my next run and I’m considering slipping a 750DE HPS between them.. If I did so I would probably change out the 3200 630DE lamps for the 4000K as the HPS already has quite a bit of the red/orange spectrum going on. I could just get another CMH but I’m interested to see what the mix of lights might provide both yield and quality wise. Is anyone out there running a similar mix to what I’m thinking of..? I’d really like to hear some real world experiences if possible.. I think it might be a pretty nice setup.
