There is a manufacturer making FFB bases, although for a hefty price and designed for thrustmaster-standard sticks
https://youtu.be/GcmZB5-oGEUApparently there were patent issues because some douchebag decided to patent troll the industry in such way that sub-$100 FFB joysticks became nonviable, resulting in the existing FFB joysticks disappearing which resulted in very few games supporting it, resulting in no major manufacturer offering them.
Even back then, the only big names I know were making them were Logitech and Microsoft, I couldn't find any old Thrustmaster joystick with FFB support. If they are to make it, then VKB should be making a developer program offering joysticks free or at a discount to developers making space or flight sims (or mech sims, why not?), and try contacting developers of games such as Kerbal Space Program, XPlane, Elite: Dangerous to see if they're interested.
On that note, they should have a FFB gladiator as well, first that it would be much more straightforward to implement because it's not required to have heavy-duty components and it would be much easier to convince developers to develop for it when it isn't restricted to gamers with high budgets for their sim rigs, I would not expect a FFB gunfighter base to be any lower than U$600
