Taking that model as reference point, what would be a good improved weapons fit for a possible Pakistani built future F22P “batch 2”?

How about RAM or SeaRAM front and rear, or Phalanx forward with RAM rear, or front 1x Mk41 (32 ESSM) with rear RAM/SeaRAM? Other possibilities would be using South African Umkhonto or a European missile like SeaWolf or MICA VL (which uses the same launch tube as Seawolf). Would Sylver VLU + Aster 15 forward be a possibility or too much for a 2400 ton ship? Replacement of twin 100mm gun with a (used?) UK 4,5″ gun or a modern Chinese single 100mm? Replacement of AK630 (by what?)?

Ideas/suggestions anyone?
