I swear I keep going on and on about how perfect this misc looks (because if this got into the Blue Moon collection, I'd probably never use any other Demoman misc ever)
But at the very least this could potentially come with a style to hide the grenade bandolier for a smoother, cleaner look or update the models/materials a tad to remove them from the start!

I even tried to "photoshop" a new design for this: https://imgur.com/a/x2fEH
