strange s15 oem hid question

[Q.Smooth127]

ok strange issue.
so im gonna be buying someones passenger side oem hid s15 headlight and then someones driverside oem NON hid s15 headlight...
question is would it be possible if i took the ballast, projector housing and hid bulb from the broken driver side oem HID light and get that stuff to fit into the non oem hid one?
I was plannin to drill a hole in the bottom of the headlight area where you would mount the ballast (cause apparently thats what it looks like how the oem setup is, they have a hole at the bottom of the headlight where the hid bulb n harness fishes thru into the headlight internally and then the ballast covers the hole at the bottom?)
Ya i could spend like $700 for a new driver side OEM hid one to match the good passenger side one but thats a lot of fricken money just for a headlight (yes i actually thought of just buyin a new hid one). But came across this deal and wondered if its possible?

any s15 oem hid gurus out there can help a fella out and lmk.
thanks.
