We have a project like that in the freezer.
The chances of really making it are almost zero because it is extremely complex and expensive. The final product would cost more than a fully automatic, full size washing machine because of the complexity of the motor, the transmission system and the suspension, to make possible to reach 3200 RPM and at the same time be able to reach low speed to wash.
As I always say, nothing is "impossible" for engineering, as soon as you can pay for it.
And in a world where millennials only care about tag price, not the product value, it's really hard to fight those Chinese companies. What matters more, nowadays, is the Amazon ratings and the product positioning on Amazon's screen.
And a simulation considering the sales "out of amazon", to break even (no profit, just covering our costs) the MSRP would have to be over $1500. Who would pay that for a spin dryer just because it can also wash?
Obs. Those silly Chinese washers with a spin drum can reach "impressive" 250 to 300 rpm and they don't last much because the motor (a wash motor) is always overloaded. Even if they reached 500 RPM, the drum diameter is so minimalist that the result would be worse than a WCI Skinny Mini spinning on "delicate"
