Extremely difficult to justify given the great synergy between Stealth and The Turning Wheel, and the additional costs to use this. Shapers would be using it almost exclusively for HQ, but then why not just play HQ Interface if you need that effect? Or The Gauntlet? You'll save credits and influence. Criminals would be using it for R&D, but at 2 stealth credits per use, that gets extremely expensive very quickly, and Criminals don't get Net Mercur in faction, nor get to be Smoke (note that DJ Fenris doesn't gain the Stealth subtype even if he copies Smoke.)

So the only case I see this being used is in a Criminal Stealth deck with access to a huge surplus of stealth credits that can't afford influence for R&D Interface or any other R&D multiaccess for some reason. But then they're probably spending a bunch of influence on stealth credit sources, and they could shift some influence away from stealth credits toward R&D multiaccess. One R&D Interface or two The Turning Wheels would likely be enough.

With the additional costs and the 3 influence requirement, I don't think this is playable.
