That is a great bulk set up for that spot. In my opinion, going head to head, cranes will regularly out gross bulk racks just because they take bills, the game play is more exciting and the chance of winning a big prize is often too hard to pass up. Since you have operated cranes in the past, you know it is a completely different animal than bulk vending. Cranes can make great money but require a lot more attention and capital to operate. Generally, if you are going to delve into that business, it's not a bad idea buy several of them and put together a small route. That way you can buy more mixes and rotate items from location to location. If I were going to add one there, I would swap out the sticker machine for the mini crane (if it will fit) and leave the rack. You would also need to bolt it to the wall or floor.
I guess my ultimate advice would be to ask yourself where you want to be in vending 5 years from now. Is this something you really want to expand on or is it just a side gig for the foreseeable future? Bulk vending is a lot less demanding than a claw machine route but claw machines have a better future than bulk. If it is a just going to be a side gig, I would stick with bulk for the time being.
