Well, it has the two males/two females thing going for it, but that's about it.
For this to happen, Jessie and James would have to give up capturing Pikachu (which in my opinion would only happen if Team Rocket broke up), and then Ash would have to accept them in his group (after 500+ episodes of them tricking him and stealing his Pokemon).
Besides, something tells me that they're gonna eventually become "stale" if
they permanently join up with Ash.
I'm sorry guys but I'm just sick and tired of getting used to one girl and than getting rid of her. And I'm really starting to like Dawn/Hikari at least this way we'd know Jessie and have had her forever.
But with this idea, we'd have to get rid of Dawn, meaning another girl would leave. I don't see a point in replacing Dawn with a
third coordinator. Especially someone who was never really in danger of being gone anyway.
I'd rather just get used to Dawn. (And keep her as the permanent main girl character. Jessie's a
woman, to be specific.) I prefered that May stayed the whole time, but with Dawn here, we should just keep her.
About Meowth he'd be on the team too. And we'd get new villains, some thing you guy's tend to complaine about.
We can still have new villians with Team Rocket as enemies (just like with Team Agua and Team Magma).
