Where's the Thrust? If the Thrust is "ahead" of the deadweight, it's pulling, if it's "behind" the deadweight, it's pushing.

Yes!

And as long as you have two hands on the club as per driveloading or extencior action, you will have a two sided thrust. One side pushing and the other side pulling, whether you hit or swing.

Most of the 24 Components already are the same with Swinging and Hitting.

Precicely.

I don't think you can become a good hitter without mastering most of the swing fundamentals.

You can replace some of the pivot motion range perhaps with a right hand thrust but you still need a lively and connected pivot to get anything out of that thrust. And as long as you turn those shoulders, there will be rope handling that creates swing speed, whether the other side axes or not.
