I'm not sure what you want here. This has nothing to do with Parameter
Expansion, and the HISTORY EXPANSION section of the bash manual notes that:

and

So you may consider as though the bash parser never read your parameter
expansion, because the input stream parser modified it first.

P.S. As usual, please stop top-posting.
