Never tried to cut the glass on miniature tubes. Like you I have salvaged
octal bases to make connectors. But for you puropse, how about an
old-fashioned socket saver? Would not that do what you want? This place
says they got 'em.

Subject: [Boatanchors] Has anyone ever cut the glass top off a miniature
tube to re-use the base?
Yes, this is another stab at finding a source for 7 and 9 pin miniature
tube plugs. Has anyone ever 'de-vacuumed' a mniature tube, cut off the
top
using a glass cutter and then soldered to the pins?
I think I could get the glass off (leaving, say, a 1/4" rim on the bottom)
and cut off the tube guts. But I have my doubts about whether or not the
leads coming up would take solder. I rather imagine the leads were spot
welded originally and that the leads may not be solderable.
Any thoughts? Anybody done it?
