The request has some merit (so I've upvoted it), but in a sense it's already happening. Traffic on Meta Stack Exchange is three times the usual, and users are upvoting (and downvoting) much more often than they did: about ten times the usual according to this SEDE query:
Most of those are upvotes, and those give a lot more reputation than downvotes cost anyway. Therefore, users are gaining much more reputation than normal (I've rep capped every day since September 30th without even trying to) and are gaining privileges much earlier than normal.
For the vote counts, you can use install a userscript or if that doesn't work for you, view the timeline. Deleted posts are deleted for a reason, and if deleting a post really raises some questions, other users will post a question about the deletion anyway (example 1, example 2). Basically, the only thing you miss by not viewing deleted posts is more drama.
