I think that an auto-highlight-on-move, similar to mashing CTRL constantly on Windows, only with the screen-darkening ability of the double-CTRL-tap of Microsoft Powertoys, would be more effective for you. As in, with every significant (user-magnitude-defined) motion of the mouse, all screens darken/grey-out except for a bright spotlight surrounding your mouse. Allows you to always see where your mouse is even up to near-blindness, as that spotlight is going to be 3-6cm in diameter regardless of the screen resolution, and obvious as heck. Edit: been looking for a tool like this myself. Still have decent vision, but with six monitors at ≈1.5-2k resolution each, a cursor can go missing, fast. Would love to have cursor highlighting (no stupid Win98 “tail”, thanks) on any mouse movement.
