Is there any reason layer comps won’t work for this? This is one of the big reasons it’s a Photoshop feature. With Layer Comps, you can A/B test not just two different adjustment layers, but any visibility combination of any number of layers. And you can make more layer comps of other layer combos, so that you can do A/B/C/D/E… testing.
The basic idea is that you enable any set of layers, then create a layer comp of that. Then you enable any other combination of layers, and create a layer comp of that. Finally, you can click between the layer comps to enable each saved combination of layer visibility. Optionally, a layer comp can also remember the position, appearance, etc. of its visible layers.

I also like the History snapshots idea suggested earlier, because they might be quicker and easier to set up for this purpose if you don’t need to save them with the document, since your goal is to delete one of the layers. Layer Comps are saved with a document, in case you want them to be there in the future.
