Maybe because you're incorrect about the AMS being the problem? The AMS merely feeds the correct filament. It's not the fault of the AMS that the printer doesn't have multiple nozzles.

The problem with the AMS is it feeds all the filaments into one nozzle so it requires a purge every time the color changes. There are other filament spool designs without this problem.
