The beatmap switch is a good idea. I like it.
I'm not too sure increasing the window of miss would work too well. You'd accidentally miss a note that wasn't even on the screen, then when that note comes on screen you try to hit it again, and end up getting a miss for the note that's after that and so on. I know you're going for simplicity, but it just isn't going to work here. Instead you should be punished, but still able to hit the next note.
The hold thing seems good on paper, but in practice it's not that good. You have more precise control over pressing a button down than releasing it. The thing that you have the most control over should be what's most emphasized for scoring.
So the timing window for releasing a long note should be less strict than for pressing it. In exchange, the release of a long note should never improve your score for the long note. If you press with 320 accuracy and release with 320 accuracy, you get 320. If you press with 320 accuracy and release with 200 accuracy, you get 200. If you press with 200 accuracy and release with 320 accuracy, you get 200.
This also keeps the mindset of the player in the right place. With the averaging thing, you're encouraging players to think "oh crap I hit that badly better release it exactly on time to get the best score from it". With the emphasis on hitting the start of the long note instead, you're encouraging players to always hit the notes at the right time, and stay in beat with the song.

I don't like idea of breaking on 50/100 and I'd make judgement on normal notes harder including rainbow 300's. Then I would only play hard mode
Your combo (specifically, that number with the X after it at the top of the playfield) doesn't affect your score whatsoever (look up osu!mania scoring if you don't believe me). So breaking your combo is just a visual thing. We could even add combo breaks on 50 in the current osu!mania and it wouldn't change anything (except give you a bit better feedback on doing badly).
