The IAF MKI fleet is massive and dedicating a few sqds to Air superiority as a primary mission might not be a bad idea: Equip these birds with the best IRST, radar, engine package available even if it means a slightly different supply chain. What i'd really like to see here:
1) L-band radar in wing edges (and possibly vert. stabilizers) for ultra long detection - AWACS type duties.
2) Full spectrum, internal EW suite - allowing for passive detection/tracking (I think the latest on the Su-35 allows for aerial tracking of targets passively).
3) TV/IIR channel IRST
4) RCS reduction: use of composites, RAM, and Conformal carriage of weapons, at least 6 AAMs - not necessarily in internal bays
5) VLRAAMs - 200km
6) High powered engines than current AL-31FPs and 3D TVC, allowing for higher ceiling
7) Super powerful radar - either the Bars II or a full AESA allowing for detection of 1-3msq targets @ 450km. Fully capable of guiding 200-300km AAMs.

9) Greater amount of fuel capacity either by increasing internal fuel to Su-35 standard OR by adding plumbing for EFTs, or adding a "humpback" CFT ala MiG-29SMT or even getting rid of WSO and substituting fuel ala MiG-29K
What am I missing? I think a bird of this nature has the best chance of detecting VLO type threats. The EF too will be good, but the pure raw power available through a flanker platform makes it the best non VLO platform vs. stealth targets imo. If not anything else, at least it should have the fuel reserves required for exiting hot zones with alacrity on full ABs.
And of course, such an a/c would be useful as a mini-AWACs platform in enemy skies - rather not see lumbering phalcons hanging about in such zones. A few dedicated birds will go a long ways in imposing the necessary NFZ over TSP for eg.
