In other words, the two characters are still working on different resource schedules. What you suggest doesn't HURT, but in the context of "revamping 5e to work like 4e" its not getting you much. Its obviously personal taste, but I like EVERYTHING pretty much about 4e better. I mean, there are some things that are fine in 5e, but that doesn't mean they wouldn't improve if they were more like what's in 4e! (at least for the purpose of playing 4e). I don't see ANY point where 5e advanced the art of 4e. A 5e-informed 4.5e could certainly gain, as I've said, but the small bits of 5e-isms I'd pull in wouldn't warrant basing it on 5e.
Well, I'd revamp Wizard too, to essentially be a Warlock build that exchanges Warlock spell list/invocations for a better spell list+Wizard school+and some daily slots that can be used for extra spells.
I don't think it helps me that much, but it makes it a lot easier to run a 1 encounter day in 5e without it being complete rocket tag.
