No, I don't think that. I think the investigation will die as soon as the GoP gets a House majority in the next midterm.

Exactly what do you expect to happen? No GoP politician in "good standing" will grant validity to anything that comes out of the committee. No Cult members will be convinced by any amount of any kind of evidence. Independents might agree that Trump is a PoS, but then many did not vote for him at the time... but they will still vote for other Republicans now because... inflation, wokeness, the socialism, or any other excuse--because the LAST thing they want to admit is that the Republic is in actual danger.

The committee will come out with some findings, which pretty much every GoP politician and media personality will dismiss as a partisan attack and a bunch of lies. They will be believed by those who want to believe. Some minor players may be charged by the DoJ. None of the major players will be. This will all drag through the court system multiple times until it gets memory holed or the GoP retakes power.

There is no will to actually do much in response to any of this. The large number of people in the middle voted for a return to normalcy (LOL) and are busy trying to pretend everything is normal and that none of these scumbags actually means what they say. I am sure many of the politicians don't mean much of what they say--but the fact that they have to say it says something in and of itself. These politicians do not actually have any control and exercise zero leadership--they follow the demands of the mob, which are echoes of what Trump and the Right media push... The media is just trying to make money--but Trump and a number of his followers mean what they say and say what they want.

Mobs are notoriously fickle, stupid, and prone to violence.

I expect a full blown disaster over the next few years because sane people lack the courage to act or the ability to act effectively (if they do have the courage).
