You're asking for a Destroyer with those requirements.
Type-054B is supposed to have a very good radar that is significantly superior to 054A. So, my guess is that it should be able to support a much superior Air Defense missile. Something akin to HQ-9C which is significantly smaller and thinner than HQ-9B. This will be a good capability upgrade for Type 054B or its successor.
Another important armament to upgrade will be the slant launcher for YJ-83. Replacing YJ-83 with a small but capable hypersonic missile will be significant upgrade. Yj-19 should be small enough to be able to be carried by the frigate.
This is still a much lower level capability than UVLS capable destroyers of the PLA. Which can carry bigger sized missiles such as YJ-17 and YJ-20 along with much bigger Air/Missile defense missiles. PLA is integrating HQ-19 for naval missile defense into its destroyers for example.
PLA frigates should be the more numerous second line defender for PLA carrier strike groups and amphib strike groups. They can also act as convoy escorts.
With these armament upgrades, PLA frigates should much more capable without falling into destroyer level capability.
