Here's an old post I made on the subject,
To avoid confusion, I suggest we refer to the various fonts also by their heights from now on. In this way, the usual Doom fonts in the STCFNxx lumps would be 7-px tall.
all letters obtainable except B, X, and Z.
Menus use a combination of 15-px fonts ("big caps") and 12-px fonts ("small caps"). Some "big caps" like the letter "Q" are actually 17 px.
Level names that appear in the intermission screen seem to use the same 12-px font as the menus' "small caps", but with a white palette. STTNUMx graphics are 16-px tall, and WINUMx ones are 12-px tall. When using only 15-px tall fonts, STTNUMx digits (16-px tall) could be used with no problem, I suppose.
Now, the letters "B" and "X" in their 12-px versions seem obtainable: "B" can be found in several places (e.g. Tower Of Babel, Hell Beneath, Deimos LaB etc.) and "X" can be found from "Sfx Volume". No 15-px instance, though, and Z doesn't seem to be available in either size.
However, there might be a workaround: a 15-unit tall X could be fabricated programmatically by using the right half of a 15-unit "K" or the top part of a 15-px "Y". Also, "Z" in both sizes can be fabricated as a sideways "N". A "B" might might fabricated by using the top halves of either an "R" or a "P" (plus perhaps some retouching on the lower part, so it's "closed"). Also, individual "dots" can be derived from the various 12px and 16px percent graphics, as well as "slash" and "backslash" graphics.
Edit: now that I think about it, the above ^ is pretty sad. Just include a ready-made PWAD and fuck the whiners ;-)
