Probably your easiest retrofit is lamps with radar built-in, though the
end-firing lamps might not work best with a bulkhead style shade, also I'd
worry about the lifetime of cheap chinese LEDs being enclosed and getting
hot.

if they came in a "stick" form bulb you might be right

fitting a glob into the space available is going to be too much of a rework
inside the case, I fear

(Not sure what you mean by "end firing")
