I loved the proposals for both passive and tactical. If anything, I'd say the passive would be incredibly powerful and might well more than make up for the loss of skyward dive. It's only the ultimate that I'm wary of, and not because I think it would be a bad idea - only because I'd be sorry to give up the current ult.
As far as her skyward dive height... they only bumped it up a few months ago, so if they choose to walk some of that back then I'm okay with it. I will only say that I think they should nerf the mobile jump tower now. There shouldn't be a situation where anyone in the game can get a pick up that's just as powerful as her ultimate. Close, sure. But not as.
