On one hand, the thought of them being near-identical because they're basically the same person from two different dimensions, has some interesting underpinnings which could make for good storytelling.

On the other, this is 2023 and parallel universe doppelgangers hanging out has completely been done to death for decades now, and so you're left with two near-identical blonde Kryptonians co-existing and stepping all over each other's niche as Superman's cousin.

In the past, they either existed on two different worlds (pre-Crisis) or only one at a time (post-Crisis) or they just never really overlapped despite their similarities so it didn't matter. Now that DC is like ALL SUPERPEOPLE MUST LIVE IN METROPOLIS, YES EVEN THE CHINESE ONE and there's this very visible attempt to find ways to tell Supergirl from Power Girl, Kon-El from Jon, and so forth.

I still maintain that at this point, when PG loses the boob window, she's no longer Power Girl at all, since of all her traits, that's the most dominant one left. (I know they've gotten rid of it before, but never when we were at risk of confusing her with Supergirl. Oh, and of course it doesn't help that now PG wears the Superman... er, House of El "S" crest like the rest of them. At least in the past, her refusal to claim his logo was another deafferenting trait.
