I'd be wary of buffing Ephemeral Insight anymore than bypassing all forms of elemental mitigation other than things like Sayakana. The whole reason Charge Mind got adjusted is because it was so powerful of a pre-engage buff.

It'd make it so that when you engaged on someone who had CM'd prior you'd usually just die immediately since they'd preloaded an entire extra round of damage.

On the surface, yeah, only making your damage Akashic doesn't sound great. Its purpose is bypassing elemental resistance/nullification you'd otherwise be running into. Of course you aren't going to use this if your target does not heavily resist or nullify your damage type. Otherwise it's extremely potent if your build is heavily reliant on boosting one damage type or you really don't have anything better to do for prepping.

Making it any better universally risks it becoming what old CM was. Watching Evoker instantly kill people because the map was so big it allowed them to prep long enough to kill you immediately on engage.
