They need a general transport/air assault version of the Z-18 imo. They've developed it into good AEW, ASW, and VIP variants, they should now develop a general transport.
It has good payload and internal volume, and with the modern construction methods, avionics, and cockpit, they can definitely do a good makeover of the original super frelon. Also they should look to stick two or three GPMGs for the ramp and sides, along with the usual suite of counter measures, radar, FLIR, etc. I'm sure it would be a hit on the export market too, and give performance in the merlin class.
