Is creation of the commission dependent on Congress doing it? Is that subject to a filibuster? I'm not sure it is, since it doesn't require a bill to become a law. Could be that a simple majority is enough. But it could be done as a House investigation. The Senate has no say over House investigations. That could be totally controlled by Democrats, so maybe a threat to do a House investigation will get Republicans on a non-partisan non-congressperson commission.

We're flying electric helicopters on Mars yet you can't turn on your clothes dryer in Texas. That's because scientists are in charge of Mars, and Republicans are in charge of Texas.
