Consider an extra item: a new-mount combined adapter and teleconverter.

That wouldn't be any use as a teleconverter for new-mount lenses. But I don't believe Pentax should bother developing the sort of new-mount lenses for which teleconverters are applicable. Teleconverters tend to most useful for longer lenses. And those should be K-mount lenses, suitable for SLRs as well as new-mount cameras.

A combined adapter and FF teleconverter might be about 25mm front to back, whereas a separate FF teleconverter attached to an adapter might total 45mm front to back. The combined item would be lighter and cheaper.

A tele converter could also allow APS-C lenses to cover full frame...
