Short answer to your question is no.

Magnification requires multiple optical lenses which creates an "eye box", the specific distance between eye and optic that you need to see a clear picture. You can't use binoculars held two feet away from your face, for example. This is difficult to implement on a handgun because of the variability in how different people hold handguns, especially in more dynamic shooting. It may be near impossible because of the size constraints of the pistol red dot format.

You could opt to use a more traditional handgun scope but you'd be looking at an...interesting mounting solution that is not conducive to being carried in a holster. Think the .45 Longslide from Terminator 1.

Not really. The expected common uses for a pistol with a mini-dot don't really mesh with 1.5x magnification. Dedicated scopes exist as I'm sure you know, but they don't come in the same footprint as a dot.

Normally eyesight issues with pistols come down to seeing the reticles not the targets. If you can't see a 15 yard target, then that really becomes more of an optometrist's problem to solve.

People with astigmatism normally can find a workable pistol red dot, since with the reticle being so much further away than on a rifle, the light streaking or blobbing tends not to be as bad. You can check out a few brands in person to find one that looks crisp and doesn't have a refresh rate your eyes hate. If you really have serious red dot issues, the next best thing is something like a SeeAll open sight.

I know on rifle applications, if you want mag you simply add a fixed magnifier (usually with a flip in/out) behind your red dot like so: But that's obviously not practical or possible on a pistol. Plus typically these forms of magnification require specific eye releif distances that are closer than arm-outstretched length.
