Do you think a Bard of Void would be able to create small black holes, generate objects that would "fill a void", or something else entirely?

Destroying through Void and Destroying a Void, sounds appropriate enough. Black Holes do seem Voidy and Destructive enough, and we do know that ‘removing nonexistence’ definitely works to summon items. Maybe to make it different from Roxy’s, you could have them literally filling an empty space, like, being able to fill in the shape of something- Effectively lockpicking any and all locks by destroying the void inside the keyhole with material and turning it, or filling in silhouettes of any kind.
