I think PAF will probably acquire more CN-235 for tactical/short-lift transport purposes, it is a good platform. As for medium-lift, I think it'll end up requesting more used C-130s through EDA.
In the long-term (i.e. after 2025) the PAF could begin replacing its C-130s with a new generation platform, maybe the Embraer KC-390. The benefit of KC-390 is that it can be acquired in both transport and tanker variants, and I believe (not sure yet) be converted between the two roles. PAF can begin replacing C-130s and IL-78s with a single platform 12-15 years from now, thus saving in terms of logistics, maintenance, operation costs, etc. In fact if pursued correctly, PAC could even become an industrial partner and supplier of certain parts and segments of KC-390.
The C-295 would be a good intermediate transport in the short-lift role, but it can also be used as a platform for special-mission aircraft. For example, one of the likely gains from the ZDK03 program with China is acquiring the knowledge and capability to integrate the AEW&C system to a platform of our choice. It is possible that PAF will try equipping an aircraft such as C-295, ATR-72 or even ERJ-145 with the ZDK03 (or a future variant of this system) for both domestic and export purposes. The C-295 (or ATR-72, ERJ-145) could be a potential platform for not only AEW&C, but also ELINT, STAR (Surveillance, Targeting, Acquisition & Reconnaissance), maritime surveillance (replace PN Fokker F27).
