Leaning towards yes. The Wisconsin Democratic Party certainly seems to be taking this seriously (you don’t drop $4 million on an ad blitz against a nonesistent threat). The legislature has already shown a willingness to engage in institutional warfare and undermine the other branches of government when it didn’t align with its agenda.
Even if they do its a no win. Evers picks a replacement. They can;t stonewall because Hagedorn won't stand for it.
Would Evers be allowed to just appoint Janet again?
I don't see why he couldn't and in my opinion he should.
The plan is to never hold a trial. Once impeached she would be suspended until cleared in a Senate trial. Senate Republicans would either never hold a trial or wait until Republicans win back the governorship to remove her from office, keeping the 3-3 conservative split in place in the meantime. Democrats can sue in federal court but Samuel Alito has already signaled that he would rule to keep Republicans in power under the nuh-uh doctrine.
