What a 5,000-6,200-ton Perry would become

What capability could be added if the Perry displaced 5,000 to 6,200 tons?

Many major additions would become possible, but that much extra displacement would fundamentally change the design and undermine its role as a basic frigate.

Raising displacement from roughly 4,000 tons to 5,000-6,200 tons adds about 25-50 percent and changes the ship's nature. The extra margin could support another launcher, a 5-inch gun, or other major capability, but the result would no longer be a modest evolution. Requirements discipline is the issue: attractive additions can erase the cost and force-structure role that justified the basic frigate. At that scale, a modified Perry becomes a new ship.
