What do you mean Awakening's format, like having 6 + 7 as 2nd and 1st generations in one game? I think they are already doing the best they could with remakes by keeping SOV's gameplay as close as possible to Gaiden while spicing it up with experimental things like combat arts and now series-staple supports, plus a modern coat of paint (NES games just look nasty.)
I can understand introducing things like pair-up to games without it, reclassing for replayability, casual mode, more supports etc. but having every remake fit into an Awakening cookie cutter just doesn't seem logical for most games' story and gameplay structures. The biggest things to get people to play these games are accessibility and marketing. Before Awakening more than half of the franchise was literally Japan-exclusive and the other half was marketed like ****. Who's gonna play an unknown IP that they have no nostalgia for that's in a niche genre? I think the groundwork they have laid with Heroes will do just fine to keep getting people interested in the older titles as they are remade and released on Virtual Console.
