That looks pretty cool but I personally think just globbing old style parts onto new bikes is kinda a design cop out. Its inauthentic, that bike will never be Nixon's H2; its shares nothing with it except name. I totally get that the factory design may not to be some peoples taste either. IMHO the ideal aesthetic is making something that suits the period of the bike with a nod to the past. Its like when people put 20" rims on classic cars; it looks out of place. In reality that front fairing would probably look super weird from the front to accommodate for those large intake tracts. I'm gonna paraphrase here but Shinya Kimura once said something like "You shouldn't design for the past, you should look to it for inspiration and design for the future."
it is a cool concept tho, just seems predictable. thats my $.02
