oh well, i dont think that its possible, because theres too much time that has passed between peak of oldschool goa and music of today, so giving something new the name of goa while it might not have that typical sound would simply look indeed something like kicking a dead body, artificial and pretentious. sure perhaps having common thought/ideas/spirit etc would make it "goa", but who cares how its called , do we have to force that name, afterall is goa trance about name? i know that i dont care that much about name [ok, hardcoregayporn trance aint going to grab my attention, but you get the point, i assume ], as long as it has something that grabs me etc.
perhaps to some the classical meaning of goa might seem dead while for others its still alive and something new that comes in is goa for them aswell, not because for the sake of name but because of that music-its story/soul/spirit/trip/experience and all that other blah blah blah and so on
