Is there any reason a panel or loadcenter should not be used as the disconnect mean for a bank of mechanical equipment rather than a trough and disconnect switches?

It is common practice to use a panel for the disconnecting means when a group of equipment is located together and complies with the "within sight" definition of the NEC. This is obviously a large cost savings, and I have value engineered this in to more than one project we have done.
In general and regarding code compliance, none that I can think of.
In my experience, fusible disconnecting means are sometimes required as some equipment has only been listed for fusible protection and some motor starter and other applications specify certain size and types of fuses to address withstand ratings.

a fairly common practice, and a cost effective, compact, and simple solution as well. as solutions go, it has a lot going for it.
you may occasionally find odd ball equipment that is marked only for fuses as OCP. You can add some class J or CC fuseholders in a small j-box downstream of the CB if needed.
