There has been a report of an A-50 AWACS flying over Syria:Thanks for the footage Haavarla.
Indeed the Su-35S+RVV-AE could become a game changer (if hostilities broke out). But I believe that it is more so due to the multiple track/engagement capability that the the aforementioned combo brings into play, than the range of the missile per se. The ECM pods are also a very interesting detail.
Do Russian forces have any AWAC/GCI dedicated platforms in Syria? I didn't find anything about that, but I do recall there being some ground based radars (besides the ones used by SAM batteries).

I wonder if an A-50 can guide RVV-AE.
