Yes, this is a once in a century political realignment of a political party.
There will of course be many overlaps with the old Republican party, but there will be some clear differences that will dramatically shift the electoral map.
the hard line conservatives are not gonna be happy with the new “GOP” taking in refugees from the democrat party who can’t see themselves voting for a felonious corrupt pandering old harpy, or an aged communist hippy who looks like he sleeps on a park bench and talks like he’s on a soap box in Hyde Park
