I am assuming the President and Republicans had already thought about this and will be initiating their plan tomorrow morning .
Whatever the "plan" is, at this point is is just fodder for news and the court of public opinion. Trump can certainly mount a defense outside of Congress and the senate. His lawyers are working on a written answer to the impeachment in the event that the House sends managers to the senate.
The House is really a joke. Everything it is doing is "out of order." It's playing catch-up with the dysfunctional Senate.
