No, i think, such as system is only viable and economical if it is very long range system for all threat spectrums, otherwise, it is economical to have dedicated system variants of different roles so that they can be spread fielded at locations which are subject more to a specific type of threat.
Eg : You field a battery of a multirole air defence system in peshawar but the anti ship capabilities are useless from that area, as well as most probably air to ground as well. So better to have variants, in strength, spread them out as per requirement, they could be multirole as well at points as well as dedicated at other points. Fielding a multirole system, when it gets suppressed, you lose it all, instead, field a HQ-16, some KMs ahead of HQ-9, one goes down, the other is live !!
In time, they will prove even more of a threat than PL-15, can’t wait to see india even further butt hurt once we get those beauties China is developing...
