Actually I'm using one of each type of the glowing runes except the white one, so that would mean a lot of editing (though I would be super grateful if you were feeling generous - I am a composer so I would be happy to write you a little music in return!).
Since then I've decided to make the rune smaller and have it float above the head of the unit (which changes nothing - I still need them not to be floating so high off the ground), and rotate slowly in place. Tried it using a periodic trigger and a dummy unit but I can't get them to rotate quite right (they are lopsided).
I tried to find the "glowing rune" variations in Magos' model editor but I could only find 3 base runes with no FX or colour (strange), and I would have big trouble moving them around and adding an animation since I have little model editing experience and zero experience with animations (and no program).
If you'd like to see what I'm doing, PM me and I'll send you a copy of the map so you can have a look at my "makeshift" method.
BTW, thanks a ton for your comments/helpfulness, bro!
