I see Nova have a new chuck (really a new jaw carrier) system out.http://www.novainfinitychuck.com/
Although inserted from the side, the jaws are locked into place by pins so should not affect the chuck's ability to work in reverse. Record plans to stock these but do not have any prices yet. They will be producing a promo catalogue some time in the new year.
