SLS IA brought back?

[_Augustus_]

Since NASA isn't getting much funding or directives for the SLS Block IB, might we see a return of the IA?

I don't see what problem that would solve. There aren't more payloads for the Block IA than for the IB.

Um, what is the 1A? Is it the one with the advanced boosters and no upper stage or the other way around ? Edit: I found out. It's without the upper stage

1A wouldn't be any cheaper than 1B, it was just another upgrade path they were considering. They went with 1B because the accelerations with 1A would be too high and they'd have to add extra structural margin.
