Scary scenario for Trump victory

OK then probably the scenario described in the OP will fail. Even if the GOP legitmately (or illegitmately as described in the OP) end up in control of house and senate on Jan 6th 2025, they won’t control the VP, so it will likely fail.

I’d put money on the fact at least one spurious objection will be entered if Trump loses, a decent chance that they’ll be more than the 1/5 threshold if a democratic VP wasn’t around to rule them out of order. Which is still completely bonkers situation to be in (and even more bonkers that the likely GOP candidate for VP has said out loud she would go ahead and sabotage the vote count, if Trump winds and something like this happens in 2029)
