I was thinking of adding this to my K2SEBZ(and bismuth!) game, is this compatible with all of those mods?

Nope, but if you're talking about that mod(pack) that adds element(s) to the game, yeah I think it's a nice "vanil-ish" concept, I could do something about it.
Sorry if the reply came with a "slight" delay, university is keeping me busy.

Added support to Lead and Worlframite (tungsten).
Next ones in order are alluminium and titanium.

I'm excited to see the BZ mods supported by this, I was thinking of manually doing it on my end this morning. Glad I checked!

Better late than never! :D
Btw if you want to stay updated on the mods you can just check the changelogs or enter in the discord server.
I costantly update you on the state of the pack there.

Let me add some comments in this section too...

From version 2.1.0 above I worked around the compatibility of Bz mods.

Currently the mod is compatible with:

• Bz Foundry;
• Bz Lead;
• Bz Tungsten;
• Bz Titanium;

Let me quote some parts of the patch notes with some details you could find interesting for you.

Version: 2.1.0

Date: 2023.12.30
Features:
- Ev Mining drills: introduced some dependences on technologies. If you have already researched
the mk2/mk3/mk4 mining drills the respective prerequisite(s) will be researched automatically.
(This feature can be disabled via startup configs don't panic.)
- Bz Lead: Added refinement chain for the metal Lead: you can choose in the configs if you want
a simple lead chain or copper as a byproduct.
- Bz Foundry: Resprited the coal coke item since I'll be introducing coal coke myself in the game.
(And a steel refinement chain, be prepared.)
(I think I'll introduce also a resprite of the foundry.)
(In my modpack the normal steel processing recipe will remain in the game unchanged.)

Version: 2.2.0

Date: 2024.01.02
Features:
- Bz Tungsten: Added refinement chain for the metal Tungsten.
- Bz Tungsten: As an addon to the mod, and since wolframite is an iron-manganese tungstate, you
can decide to obtain iron as a byproduct of the refinement process. The ratios are the same
as in the Lead processing chain, so you can expect to obtain more tungsten if you disable this feature.

Version: 2.3.0

Date: 2024.01.04
Features:
- Bz Titanium: Added refinement chain for the metal Tungsten.
- Bz Titanium: Since titanium ores often cointain iron (see Ilmenite) and aluminium (see Anorthosite),
the Titanium refinement process can output one of these two metals as a byproduct.
I think this is another interesting addon to introduce in bz mods.
The amounts are the same as in Lead and Tungsten processing and, therefore,
to have higher titanium outputs, you need to disable this setting.

Enjoy if you didn't already!
