I believe the biggest problem is that any imaging system currently in use gets burned out by the radiation in less than two hours. Someone needs to invent a CCD that uses a ceramic chip.
We just need to go back in technology about 30 years. AFAIK, old video cameras used some sort of a tube, similar to an old radio with tubes instead of transistors.
Other wise, it would seem lead impregnated glass or a fiber-optic input (similar to the old fashioned colonoscopies where the doctor's nose got progressively closer to the patient's backside) to the CCD chip should work.
What did the Hubble use to protect its imaging electronics from the radiation of outer space since launch in 1990?
