Sorry, can't comment on concentrations other than starting with what Moersch indicates in his documentation.
Lith C is just sulfite in water
Lith D is mostly potassium bromide, but with a little nitroindazole as an additional restrainer. I wonder if you could substitute e.g. benzotriazole for the latter (I think so).
Lith E is just potassium bromide
I never used these Moersch products; instead I just kept bottles with solutions of of sulfite, bromide, chloride (sodium chloride), carbonate, hydroxide etc. at hand. Concentrations where, like, whatever. Just add some to your core developer, see what it does; if you like it, stick with it; if it's going somewhere but not quite, add some more. My core developer was a take on Ryuji Suzuki's formulas and very, very simple. Essentially it was just hydroquinone with a tiny bit of sulfite and some carbonate.
The effects of sulfite and bromide in lith development are well-documented. A good primer is here:

Props to
@grainyvision for writing that excellent overview!
All that content applies to the Moersch Lith C, D, E products just the same; see list above for the 'key' of what's what. Of course in addition to Moersch' own excellent writeups that can still be found here and there.
With lith, there really are no fixed formulas. It's inherently a seat-of-the-pants approach.
