Interludes are awesome, can we keep them for alts after release?

Straight to the point: As so many people will play multiple characters per league but don't want to do the full campaing again, can we keep the interludes as a "second campaing" for alts after you complete the original story?

We could include interludes mini chapters for 4-6 of the main campaing to have alts go for a similar experience and have all stat upgrades in a similar way.

This "Alt Campaign" can be as brutal as needed, there is not need to slow it down like the original as everyone chosing to do it should be able to handle the dificulty.

This is only a small suggestion after enjoying both the main acts and interludes. I really think we can have both of them and please a larger number of people wainting to play lot of characters on any league.
