I'm looking at the Jianghu-IV (053-HT-H/#544 Siping) with the aft helicopter deck:
IMO if such refit is cost effective for old Jianghu frigates, it might be possible to turn them into multi-mission capable patrol ships. The helicopter could be used for target acquisition, ASW, anti-shipping, or search & rescue missions.
Ripping guns and missiles out and replacing it with a helicopter deck is probably not that expensive. But if we start getting into radar, fire control, weapon system upgrades, then it'd get pricy. At minimum, the ships should replace its old AAA with modern CIWS systems.
IMO we shouldn't overlook the possibility of using ship-based helicopters as an anti-ship weapon. The successor to the AGM-119 Penguin, the Kongsberg NSM, is estimated to carry a 120 kg warhead with >150 km range.
Also, another factor to consider is that some of PRC's neighbors by the sea don't have powerful navies. For an example North Korea only has 3 light frigates with Styx SSM's, Malaysia has 4 light frigates with MM40 Exocets, and Vietnam/Philippines/Burma(Myanmar) only has patrol boats. So if the PLAN needs to send patrol frigates in those areas, you don't need more than light frigates equipped with silkworm missiles to serve as effective deterrant.
