I haven't checked it exactly, but it seems like my buildings can also produce the recipes from SEK2. So that should work out fine.
I don't think my two buildings are suitable for your mod setup. K2 already includes an advanced version of the Assembling Machine and Chemical Plant. My buildings would just be redundant.
To be honest, I don’t feel confident that I could integrate my buildings into an SEK2 setup in a way that makes sense with recipes and tech. And SE or K2 probably won’t do that on their own.
If you give me suggestions for recipes and tech, I’d be happy to check them out and implement them if appropriate.
