If I had to make my choice I’d ditch the bar for the can, or just work around it. Those bars don’t do much anyway, the firewall braces the towers just fine which is why even the R doesn’t have a bar.
It also depends what bar and where it sits, but you should be totally fine to have both
edit: looked at your bar, it’s gonna make it a pain in the ass for sure. I’m like 99% sure you’ll have to remove it to install the can, but should be able to undo it for emptying with a little maneuvering without taking stuff apart
