Eastman knew quite well the alternate slate of electors was contingent on their acceptance by the Congress. The point of the Congressional debate on Jan 6 was to present evidence that would convince the Reps and Senators that the certified electors were the result of a corrupted election process and the totals they were based on could not be certified as true and accurate.
This has been confirmed in the “Rigged” and “2000 Mules” movies but there was considerable affidavit and video evidence at the time that the popular election in several states violated state law.
The process the Eastman tried to invoke was developed for just such a scenario when the popular vote was found to be uncertifiable.
Nancy Pelosi and others knew they could not allow this Constitutional process to go forward, so they intentionally conspired with government agent provocateurs ala the kidnapping of Whitmer in MI to provoke gullible groups like Proud Boys to enter the Capitol while failing to secure access to the building. Their objective was to shut down the debate. This was the real insurrection.

Alternate slates would have been a very good idea - it fact, the Florida Legislature was prepared to do just that in 2000, had it proved necessary.
As for 2020, though, it is a myth. Pennsylvania, Georgia, Arizona, Wisconsin, and Michigan all had Republican legislatures. They were perfectly free to appoint a slate of Trump electors and send them to Congress.
But they didn't. They didn't even convene to debate it. Not one single responsible member of any of those five legislatures did ONE SINGLE THING to advance what would have been a very good idea.
They didn't do it because they didn't want to do it.
They wanted Biden, and they got him.
Well said!
