Diseqc motor - can it be fixed upside down

Question has been asked before but wondering what people think now. The idea would be to mount the motor on the mast such that the small stub pole from the motor would point upwards instead of pointing down.

As far as I can find all the popular Diseqc motors available now have the stub pole pointing down. But I thought some early Diseqc motors had the stub pole pointing upwards - are these motors still obtainable now.
