Replacing C299 or UV199 tube
#4

The above link is to John Eng, who has a wonderful website.

I would think that it is possible. You will need a blowtorch. I remember creating glassware in either High School or college chemistry.
1. Remove the base
2. Obtain a glass tube, heat the tube and the bottom "stem" of the tube. When both melt, touch together to "weld" the 2 parts together.
3. Rotate the tube heating the seam between the stem and envelope of the tube. When sufficiently hot, remove the stem and "firepolish" the envelope.

Alternatively, create a glass cutter using a length of nichrome wire suspended and powered.

If the getter changes color, rinse it out and paint the interior with silver paint.

Glue the envelope over the base after wiring the submini tube to the base and verifying operation
