Remove all the semicircular loops, add the same leg supports to the other four tori, spread out the base legs, and add diagonal struts to prevent rotational collapse, and you have my idea, Billy.
(angled legs and diagonal struts omitted for ease of modelling)
How far is the cantilever expected to be? And what is the expected force a 60 Tesla magnet will push back at? If it's high enough to rip the "nubs" apart, how is a cantilevered support going to keep it stable, particularly if it really is as heavy as 55,000kg?
My structural intuition is pretty good when it comes to buildings, this is a bit out of my field, but for that kind of weight you'd probably have to camber a cantilevered structure, trussed or not, against gravity just to account for the deflection. If a force is pushed back on it, it'd be bouncing all over the place.
I suspect, however it's supported, something's going to have to connect the coils to each other to keep them in position relative to each other, unless there's enough freedom where displacements of the coils from each other don't matter.
This, however, would avoid a lot of those engineering problems. It's why I'm curious if changing the geometry of the nubs will reduce/omit their effect on the field. Whether they're capable of being primary supports or not in this shape is almost the aside.
Edit: not that it has any basis in reality or the science of fusion/polywell, but they also look kind of like solar flares.
