I presume not since I can't find much on it, but I'm curious on why if not.
Basically let's say we have three studs A,B, and C and we wish to remove the middle stud B. Could we run 45 degree braces from each side of Stud B to A and C? I presume one would need to brace the outer sides of A and C in the same way to equalize lateral forces; along with extra sistering studs on A and C.
Hopefully ascii art below helps.

This of course would be augmented with a proper header but is meant to carry things while removing the stud avoiding the need for side support or jacks.

No. Or yes. It depends on your risk tolerance.
Because the load applies vertically (gravity goes down) there would be both bending and sliding forces at play. Unless you accommodate that with appropriately stiff boards and adequate anchoring it's asking for trouble.
Instead, a conventional header is needed. Trimmer/jack studs along the remaining studs and a properly sized header between is the only good answer. It's also possible that you could use a "flush beam", which is basically a header integrated with the floor system so that it doesn't interfere with a full-height opening in the wall.
Maybe describe your project as a whole instead of asking such a specific question.
