If they want to step up the capability then possibly switching to the active ESSM may given them access to a better seeker but would require integration. Beyond this, they would probably need to wait for the AN/MPQ-64 AESA to show up and they would also pretty much need to re-do the launcher to accommodate anything bigger than the ESSM/AMRAAM ER. The only longer ranged weapon that I can think of that could be a viable contender would be the boosted version of the IRIS-T that is nearly ready (operationally) and that would expand to about 40 km in range and about 30% higher altitude than the AMRAAM ER.
I'm not sure what you meant as AMRAAM-ER is active ESSM and it will be integrated with NASAMS first and work is actually ongoing right now:
http://www.raytheon.com/news/feature/ai ... round.htmlDesigned specifically for ground-based air defense, the AMRAAM-ER missile will be fielded as part of NASAMS. Along with Raytheon’s AN/MPQ-64 F1 Sentinel radar and Kongsberg’s Fire Distribution Center and canister launcher, the system will provide increased protection in the medium range air defense market.
I don't think Iris-T is going to have longer range or higher altitude than AMRAAM-ER. While upgraded with larger motor (AFAIK, there is no booster version under consideration) and enhanced guidance, it's smaller missile than ESSM and AFAIK, AMRAAM-ER is basically ESSM Block 2.
http://www.diehl.com/en/diehl-defence/p ... -t-sl.htmlThe new surface-to-air guided missile IRIS-T SL (Surface Launched) is an upgraded version of the IRIS-T air-to-air missile. Compared with IRIS-T, IRIS-T SL has an enhanced rocket motor, an aerodynamic hood for extended range, a data link as well as an autonomous GPS/INS navigation system.
It definitely has pretty good range and altitude coverage:

http://www.raytheon.com/capabilities/rt ... lution.pdfBlock 1 ESSM was designed to protect against anti-ship cruise missiles, air threats, and surface threats to a range of approximately 40 km
Block 2 ESSM range increase could be pretty substantial going from SARH to ARH seeker and upgraded navigation/guidance systems. I've seen presentation by Kongsberg representative several years ago that attributed ESSM with longer range and higher altitude coverage than Hawk missiles used in Hawk XXI which AFAIK can reach 40-45 km in range and 18-20 km in altitude. They should know as they have a lot of experience with both missiles.
Interestingly this pdf shows Iris-T SL missile for NASAMS:
