I’m not sure that internal consistency should be the highest priority. If it is, that implies constraints on the applicability of a moral theory (ie some questions will be undecidable). Which may be fine, just be aware of that tradeoff.
Impossibility theorems are pretty common in mathematics. Arrow’s Impossibility Theorem will apply to many ethical frameworks. Where it doesn’t, other impossibility theorems (Godel, Gibbard, Holmstrom) are likely to apply. If nothing else, reading up on this class of theorems may be interesting.
To me, the most relevant of these impossibility theorems is the Arrhenius paradox (relevant to population ethics). Unfortunately, I don’t know of any good public explanation of it.
