Title pretty much says it. Nothing wrong with the original design I just didn't like the monster aesthetic. I also prefer to use pins and heatsets wherever possible.
BOM
8x M5 Heatsets
8x M5x50mm BHCS
4x M5x18mm pins
8x M5x30mm BHCS (from original idlers)
4x Pulleys (from original idlers)
My pictures show the body of the idlers upside down because I didn't have the right length of screws. The heatset should be on top so that it won't be ripped out over time by belt tension.
