Do you think the idea of Sanskrit being unifying language of India is realistic?

Like how feasible Sanskrit language is for daily uses compare to other languages like Hindi and English??because I think in past Sanskrit use to be language of only royals and never reached normal people.I myself use to studied Sanskrit back in my school days only know very basic that's why asking posting here for a expert view on this topic. Reposting because for some reason previous post was deleted by mod.pls don't delete it again its genuine doubt and related to Sanskrit .
