Hearings would not necessarily lead to impeachment, but there would be publicity and at least many Americans would realize that we have an illegal president and corrupt party who must be voted out of office.
Do you have an alternative solution besides waiting another year and a half for rigged elections?
Yes. Legislate. Write, debate, and vote on legislation to reduce the scope and size of government, reduce spending, eliminate departments, de-fund organizatations that shouldn't be getting tax funds, etc. Force the democrats in the Senate to block the legislation or Obama to veto it. Then rather than getting lots of publicity for wasting everybody's time and money on a circus that will never go anywhere and will make the GOP look like a bunch of worthless crybabies, we would contrast the GOP as trying to drive a solution while the dems are blocking every attempt to reduce the deficit, create jobs, and put money back in the pockets of the taxpayers.
