The likelihood of any modern red fighter being developed is incredibly slim, given the current Russian attitude towards declassification. Our only hope might be for one of the many MiG-29M variants that toured airshows in the mid to late '90s looking for export customers but never really entered Russian service due to there being no money left.
Though obviously many of the systems went on to be used in more modern Russian aircraft. I think it far more likely that a moderately faithful '90s Fulcrum could be made than any of the post 2000 cutting edge Sukhois that so many users seem to badly want.
However all this dreaming is irreverent to be honest, bring on the Viggen :joystick:
