Ugh...spare me. The coolest thing about that character is the mystery. Once you start pulling back the veil, that quality is forever lost.
I don't see how that would make for an even remotely exciting figure either. There is NO WAY that iconic armor is going to fit that little tween punk at his age, so he can't possibly wear it on the show. And what's exciting about a figure of a young human boy?

What kind of self respecting bounty hunter would take orders from a little kid anyway?
Nope, not on board with this idea...I get it's a shrewd marketing ploy, but it just seems like a cheap, easy grab for some pub at the expense of the original canon.
If they want to flesh out a character with a good backstory, please have a go at Aurra Sing instead.
