Hi kingtutt the 2nd, a 24' long wall will definitely need some stabilization along the way, unless you top it with something rather rigid. For example, some engineered timbers or I-joists on their side. Most engineered beams are intended to support a vertical load. Here, your load is minimal, so even something in the 4x6 range would rather stiff. This is assuming the wall is supported at both ends.
If your wall is 2x4, you could create a long 2x10 header with a layer of 1/2" plywood inbetween. That would give you a start and reduce the size of whatever you place on top.
Can be done, let's see what the real carpenters have to say.

I was thinking that would be a good start. Since you need 3.5 inches, add some appropriately staggered osb in there to make a 24' long header. Then use shorter studs below to complete the 8' wall. By itself, I would still expect that to wobble when pushed on, but would be a lot better than just a studded wall. The next step to make it stiffer would be to add something wider across the top. Since this is not a loading problem, but one of stiffness, you could consider a multi-layer assembly of 8" strips of 7/16" osb. Staggered seams and glued flat on the top of your wall. They could be centered, or overhang either side. If you could tolerate more overhang, go with 10 or 12 inches. The wider the better and go a minimum of three layers.
I have also seen some massive laminated beams, so there exists the possibility of creating a complete 3.5" header out of 3.5" strips of osb. All glued it would be massive and I would have no idea as to how stiff it would be, but osb doesn't flex a whole lot. But 3.5 inches is not a lot of width. For my own house, I would play. If it still needed more, I would add it on top. You would want to build it in place to avoid having to lift it

The only other thing you would have to do is take pictures and share).
