Well, nothing is impossible but still i maintain that star/disney is unlikely to have 1st output deal for English version rights of for Warner Bros or Paramount film library but yes they may opt for 2nd output deal. Also Times and Sony/Zee network have just recently signed the agreement so i do not think it will expire so soon
But if indeed star/disney signs such an agreement then Sony/Zee, Times Network English Movie chs will lose out on a big thing. Although they may still have 2nd output deal in place. Even incase of Universal Pictures this happened, star/disney aired both english and hindi/regional language dubbed version of films like recent case of The Hitman's Wife Bodyguard
Even expecting Sony Pictures shifting to Star/Disney soon , do not know if it will be a 1st output or 2nd output agreement. Strangely Warner Bros films library is divided between Sony/Zee and Times Network, i still could not figure out what kind of arrangement/deal is this as even new premieres happening on both chs
Now that star/disney has signed agreement with Warner Bros for dubbex hollywood films , quite possible that they will also acquire Warner Bros bollywood films like Chandni Chowk To China, Atithhi Tum Kab Jaaoge, Phas Gaye Re Obama etc.
