I'm really not sure what exactly those mods do, but injected records are not script-related at all. I think you could use the technique to make your change to other mod recipes without explicitly requiring them as a master, but those recipes would then show up for all your users, regardless of whether or not they're using the relevant Other Mod.
[EDIT] I GUESS you could run a script that sets flags based on what mods are installed and then use those flags for recipe conditions, but the other thing is that the COBJs have that "item produced" field, so you'd end up having to fake twice as many forms for each mod you're considering. It can be super useful for things, but given the sweeping nature of what your mod seems to want to edit, it's 100% not worth the effort. SkyProc is definitely the way to go.
