Unfortunately, no, unless you have a way to cut a hole in the glass, and then you'd have to epoxy the receptacle to the glass (a
trick that's possible with some old motorcycle round headlights). The back of the sealed-beam unit only has the individual leads for the bulb terminals coming out (photo below)
You might want to replace the old ones with the Sylvania units that are brighter tan the standard ones, The H4651 for the inner (high beam only) units and the H4656 for the outer (low.high) (

As I said above, the reflectors in my old units aren’t reflecting very much (see second picture below), so even if you could get a new bulb in there it wouldn't be like new.
