iirc Tsuyo tried this once upon a time.
The problem with it, is the ML boost happens only during the manifestation.
It says: "While manifesting a power, ... "
So generically, NO is probably the best answer.
But Ardents have that sneaky no max level power thingy going on.
I'd say a Linked power could have an Overchannel help out with that kind of cheese.
Can't use Talented with it, until 2 focuses can be had.
Otherwise the damage still happens.
And this wouldn't impact the Power's Level, except for it's ML during the -festing.
You could augment it a little more.
You couldn't pick a higher level power, like a psiotheurgist build, because you aren't perpetually manifesting something.
