Question about way to modify the rear of a small chuck to suit a Toyo ML-1 Spindle

I have thought about how one would go about modifying the back of a small chuck so it would mount to a Toyo ML-1 lathe spindle. Three counterbored holes would also be required but that wouldn't be very difficult. I have this idea about using a piece of round bar in a lathe, machine to get it running true, then mount the chuck to it with the chuck jaws then bore the back to suit the spindle. Would this work? Would it be safe to bore with the chuck mounted to the round bar or am I crazy? Next question would be to ask if someone could do this as I have not been able to get another lathe yet. Details about the chuck, spindle and counterbored holes will be provided when and if this can be done. I may even go as far as having a three jaw, 4 jaw and possibly two of each done as I also have a small rotary table with dividing plates which has the same mount as the Toyo.
