We can dream of what the notion of the trinity could have become if Syriac and Aramaic had overrun the Mediterranean, rather than Greek and Latin. A clue is given by the beginning of Ode of Solomon 19, a text usually dated to the 2d c. CE:

1. A cup of milk was offered to me,
And I drank it in the sweetness of the Lord’s kindness.
2. The Son is the cup,
And the Father is He who was milked;
And the Holy Spirit is She who milked Him;
3. Because His breasts were full,
And it was desirable that His milk should be ineffectually released.
4. The Holy Spirit opened Her bosom,
and mixed the milk of the two breasts of the Father.
[…]

(translation by J. Charlesworth, The Odes of Solomon, Scholars Press, 1977, p. 82). I would have translated 3: “and there was no doubt that his milk would be poured out in sufficiency”. Still a Father doing everything in life and sustaining life, and a Son transmitting power, but at least a female Spirit. Alas, the constraints of translation were such that the LXX writers had chosen way before this text to have neuter Greek πνευμα for feminine Hebrew רוח: not ψυχή, the nightly-visited goddess. From neuter pneuma to masculine spiritus, what other option was there?
