Bent spokes can be straitened a number of ways but it generally takes a solid mounted hub to work a wheel in a press for best run out. during the process of straightening a person can bend a spoke pretty easy but as mentioned before, the stretch has to be relieved by shrinking with a torch.
A bent rim is another story. They are much more difficult to straighten. There were tools to do such work back in the spoke wheel era.

You are correct however please allow me to share this.
Before I purchased my old BeeLine straightener, I was fairly successful in using a chassis (-complete car or just chassis) to mount the wheel on. I would use a hydraulic floor jack under the front axle to barely lift the mounted wheel's rim off of the concrete. A beverage can on the floor close to the rim would indicate lateral run-out, -and a non-concentric wheel (egg-shaped) rim would be seen by the changing distance from the concrete as it was spun on the front hub. Often times I would use the weight of the chassis to my advantage when shrinking the X spokes to bring the rim back to round. Just let the out-of-round area of the rim set on the concrete in the worst area and when the spokes were shrunk, it would assist the movement, Most rims are almost always moved away from the hub cap side of the hub on lateral alignment. A strategically placed hydraulic bottle jack and a few blocks of wood can be used to push against the frame adding pressure ever so slightly to the rim while shrinking the A-1022-* Outer Spoke(s).
My past experiences say it can be done in a home shop without a press however it just takes longer and is WAY more aggravating. My straightener has all kinds of tooling to straighten edges of rims, move spokes, and place compression in multiple areas and all this really does is just make the process go much faster. I hope this gives a little motivation to at least try it on the worst wheel.
