Would writing "tetrad indices" with a distinguishing mark, such as a hat, for instance $T_{\hat{a}\hat{b}}$ be reasonably standard notation, or would it have unwanted implications, such as the $e_a$ being orthonormal? I found myself mentally adding the hats when reading your insight article just to follow it.

Interestingly enough, I don't think I've ever seen $e_a{}^b$ written as $e_\hat{a}{}^b$, though that would perhaps be more consistent notation.
