Let me see if I am reading this right:
You are using the Mercury Vapor Lamp + Lamp Holder in the Non-Ugly Incandescent Fixture, plus are mounting the Ballast remotely?
If so, that's OK as long as the Luminaire will be able to both house the Lamp, plus deal with the Lamp's heat (the Merc. Lamp will run very hot, as compared to an Incandescent Lamp).
Also, use the Mogul Base Lamp holder (if Mogul??) which was in the original HID Luminaire (fixture).
You may remotely connect the Lamp / Ballast using #12 THHN cu for the lead-in wiring.
Be sure to keep the original Conductors on the HID Lamp Socket (the High Temp jacketed wires), and connect the THHN wires to them at least 8" away from the Lamp.
You may be able to use smaller than #12 THHN cu for the lead-in wires (from the Ballast to the Lamp), depends on the distance plus the wattage.
If this HID is in reality a Pulse-Start Metal Halide lamp, then the maximum remote range is wayyyyyy shorter! Also, the use of a Long-Range Ignitor comes into effect.
