The only thing about this plan that ***** is that now every tool you have has a long tube on the bottom of it. Some things I just bolt/unbolt instead of keeping a permanent hitch which would be expensive and take up a lot of space. I also added two nuts to stabilize.
I definitely like your idea of using a nut and bolt to stabilize the vise mount in the receiver. That will eliminate the little play that could make detail work frustrating.
Like WhiteLightening, I was planning to weld nuts to the bottom of the vise plate so I would only need one vise plate and I could quickly bolt and unbolt each tool as needed. I definitely like the thumb screw idea. That will eliminate the need for tools.



Yes, that is correct...
