2 handed whirlybird

I've got bad tennis elbow in my elbow, and it makes my tantrums really painful. I was thinking after trying a whirlybird, and my elbow kept giving out (trying to pull the handle across my face), would it be possible to do a two handed whirlybird? Granted, it probably wouldn't be considered a whirlybird, but is it still possible?

I figure that part of a tantrum is having your shoulders squared-up, so you need to let go with your back hand, but with the whirlybird you're twisting, so would it really matter so much if your shoulders weren't squared up?

Let me know if anyone has any inputs, ideas, or comments on this.
