It could be, but it seems like that would depend on the brand awareness / credentials of the team writing the software. Note that KDE, Gnome, etc. have been trying to do exactly that for decades, with only marginal success.
So if you got the team that wrote the Apple Aqua UI on board to write it, and have great PR, then maybe. If you get the KDE or Gnome team, no way.
