In theory, yes. But they wouldn't have met our timeline for FGFA.
First, Su-57 needs to finish, then FGFA, then MKIzation, then production. Instead, by pushing Su-57 back, we could negotiate to develop our own industry with Western tech, like AMCA engine JV. Russia will become important later on again, after 2035, but right now we need the West. Russia has no interest in making India technologically sovereign.
The issue with Russia is that they still build jets on old philosophy. More focus on maneuverability and less focus on electronics stealth etc. They are strong in mechanical part but not in others. Had Su 57 been made more stealth and equipped with Rafale like EW and BVR, it would have emerged a like a winner. Russia do not want to work more on their planes and lives them in between which hinder them to exploit full potential of the weapon. We bought Su 30 MKI from Russia and built a batter Su 30 in the form of MKI. Here where Russia lacks.
Tom cooper in his recent interview said that Indian S 400 perform batter than Russian S400 because of batter integration with Other system. It seems that Russia lacks in the area of Military doctrine as well. Indian military planners with Russian weapons and army would have won the war against Ukraine a long ago. Recent attack on Russian air base with drone is testimony of poor Russian war planning.
