So you are not actually against what i suggested.
I do not think that it is very likely either, but we should still give feedback that reflects the best solution we can think of.
And i think the best solution regarding the divided opinions about the PS, is to have an option available for both preferences.
Either on separate weapons, or on the same.
My suggestion is,
Option A: Give the PS a base of 2 charged swings per activation (weapon no longer sucks without PC blessing; PC blessing is no longer mandatory).
Option B: Give the PS a power gauge as suggested by @Keln , but have the weapon function the way it does now, when the PC blessing is applied.
Option C: Option A for one preference + a new weapon with power gauge for the other preference.
