Make Swamp Fever's Plantation Finale much more difficult?
Make the Tank Waves harder in a way?
Tank Wave 1 = Double Tank
Tank Wave 2 = Quadruple Tank
Unsure if its possible in a way for Tank Wave 2 spawning four tanks, attempt to double the amount of health for a true challenge before Virgil's arrival?

Yes.

At the concert, have it instead get nuked.

Or airstriked

Midnight riders Save the survivors in concert !

The l4d1 crew steals your ride in the parish.

Instead of a chopper coming in the Dark Carnival finale, the Midnight Riders show up in their tour bus to save you.

Bill coming back to life in The Passing finale and hijacking the Jimmy Gibbs Jr. race car. Thus forcing the L4D2 survivors to take the sail boat instead.

Try making the cut dark carnival finale where they meet a hippy which has access to the ride to escape and he asked you to do a midnight riders finale to make him give you the ride I know that requires a voice for the hippy but it would be okay if there was no voice or just reuse the church guy's voice

l4d1 gang guns down l4d2 for absolutely no reason

Great ideas in here, lmao
