As looked at during the introduction, I have an idea for a common ancestor diverging among three descendants, one of them being a modified edition of Ȧᵹlıꞅc, another one being unknown, and the other being a mix of Oa and Dorini.
The Oa+Dorini mixture:
Consonants: m, n, ŋ, p, b, t, d, k, g, ʔ, s, x, ħ, ʕ, ɾ, ɹ, l, j, w
Vowels: a, aː, e, eː, ə, ɨː, i, iː, o, oː, u, uː
Syllable Partern: CV(ː)(R)
The R stands for resonants, and [j] and [w] cannot occur after corresponding high vowels, or before them.

Descendant 1:
Consonants: m, n, ŋ, p, t, k, ʔ, s, x, l, ʙ, r, ʀ, j, w, tˤ, kˤ, sˤ, xˤ
Vowels: a, i, ɨ, o, ai, aɨ, ao, ia, iɨ(?), io, ɨa, ɨi(?), ɨo, oa, oi, oɨ
Syllables: (C)V(C)
Synthesis: (Same as Oa.) either fusional, iso-fusional, agglutinative, iso-agglutinative, or a mix of fusional and agglutinative
Word order: SOV, with adjectives derived from verbs, and a main order being Main Modal-Negative Auxiliary-Future Auxiliary-Question Auxiliary, and the language being head-initial
