It'd be cool but so niche I can't see it being worth it. Personally I think you have to do it from the point of view of retrospective/anniversary versions with interviews/materials that honoured the work/scenes/personalities around these games - give it context, reproduce what was good, but respect the original.
But, you know what it is: For now they'd be better off continuing and improving their port, mini console efforts and general brand awareness/marketing efforts.
You never know... once a second bunch of retro loving kids grow up there might be enough people with the disposables that want to really burn some cash on some new old games and the whole thing will be finally feasible... 20 years from now it'll be like buying a repro art piece - both cool and tragic.
But at least these games were products that were meant to be (officially) copied and distributed, which for me helps combat the 'it's just a boot' arguement somewhat (presuming it is done well)... It's not like buying a Da Vinci painting copy, more like a Duchamp urinal.
In that context it'd be kind of cool if we could somehow achieve that dream of valuing these games, but not going too bonkers over the original (copies).
