I see in Figure 1 of your link that the baffles redirect the gas backwards into the stream which you imagine would retard the flow:
This already exists as the 'K' baffle stack design used in several modern suppressor designs:
Now although the example above doesn't precisely match the Tesla design you linked to, the idea of redirecting exhaust gas back 'upstream' one or two segments is already a standard.
One thing you may want to think about is that if you were to reproduce the exact Tesla design you mention, I believe that the reduction in the volume of the suppressor body would work against you. Volume has more to do with suppression than a fancy suppressor baffle stack design. Also, if you insisted on replicating the Tesla design by adding more material and volume to match, you may end up with a suppressor that's far larger, heavier, and more expensive than modern designs and ultimately offers little to no better decibel reduction than the competitors product.
What end users want are low cost suppressors with light weight and small form factor. Effective suppressors have been available for many decades for both pistols and rifles; the game these days is manufacturing a suppressor that's lightweight, inexpensive, and doesn't adversely affect barrel harmonics by being a big donk of metal.
For an integrated design (like your DeLisle carbine or an Hk MP5SD), the problem is even compounded by the limits of specifically designing the suppressor to fit one platform. End users prefer the option to use the same suppressor across multiple hosts. That's why the uniform 'Quick Detach' feature on the higher end suppressor models is a highly desirable attribute these days rather than just a novelty characteristic.
Now, if your resulting Tesla-inspired design enormously reduced report decibel levels to an unheard of low figure compared to the products already out there, then I would imagine that there would be great interest in your design. Short of a landmark achievement in decibel reduction, I think that you'll find that the traits I listed above (low cost, light weight, reduced profile) outweighs everything else for the end users.
Anyway, good luck with your brainstorming. Take note that Dr. Philip Dater from GemTech occasionally holds suppressor design seminars for industry manufacturers at Long Mountain Outfitters in Henderson Nevada.
