The case capacity appears lower on the 6.8 looking at case drawings. So twist the WSM faster and still be able to use factory shelf ammo, then you can still run the heavy reloads . This sounds better than waiting on other companies to jump on board.

How many companies would be willing to jump in when the same outcome could be accomplished with a simple rebarrel?

I am all for more choices, not less, but realistically how great a chance is there for this to succeed?

I included the 6.5 PRC drawing for reference since they are extremely close in dimensions.

It's not just the twist. It's a whole bunch of stuff. The reamer geometry and case shape and length (and width) of the throat on SAAMI spec reamers, along with COL. The WSM was not designed to shoot ultra-long projectiles with high BC and high SD. Sure, you can cram them into the case, but the SAAMI reamers used for factory rifles and standard magazine length were designed to maximize performance for bullets 130-150gr.

This new cartridge uses a very similar case, but seeks to correct the flaws in the platform. It has a faster twist, longer (and narrower) free-bore, shallower leade angle (for high BC bullets), and most importantly, the max COL is 2.955", so standard magazines will allow for long bullets to be seated long, into a target-leade-taper.
