Make the color of the cursor more bright, maybe even Neon-colored?
Or use a different/opposite color (that is also bright or that glows/pulses) from the UI HUD setting. Such as, Federation HUD is blue, so maybe an Orange (or Yellow) color on the cursor? Klingon UI HUD is red, so a brighter Green Cursor/pointer would help make it stand out. Go the opposite/complimentary color on the Color Wheel.
I suggest maybe a neon green cursor and maybe a little larger. Something along the lines of the cursor used in Star Craft. Many a PvP death has been caused by me not being able to see the darn cursor. Minor problem with an easy fix.
