Is there a dual headlight (HID + OEM) relay schematic that will allow:

HID only
OEM lighting only
Dual mode HID + OEM?

I have made a schematic, but having trouble…

Getting feedback, so I believe I have to isolate each + terminal (low and high) on the respective systems.

Is there an efficient schematic that minimizes the relays used, and does not introduce loop logic?

Would any other information be useful to elicit assistance?

If you want control of both low and high on each bulb and ballast, then you'll be using lots of relays, four on each side, and a good many switches inside, at least four.
