Below is a python script I used to generate a Mod to swap out the fonts with something less caustic. There is much room for improvement in font choice - this is the result of 45 minutes of coding, 5 minutes of testing, and 5 minutes of trying out different fonts. However, those 5 minutes did result in 0 crashes, unlike the other font mods I tried. I think they were probably just bit-rotted.

For the slightly technically minded:

Download python for windows (gogo google), paste the following into a text file, open it in python and run it using the Python GUI to create/update the mod, then enable it in the game as normal. Tweak MOD_FOLDER and BASE_FONT_FOLDER as required for your install. Once you have come up with your awesome font combos package it up as a proper mod and upload it for folks so they don't have to mess around with Python.

MOD_NAME = "YourFont"
