If you look through the mail archives, you may find that it was discussed to death back in 1993 that you cannot communicate such constants as the script and scripscript sizes through fontdimens, because the fontdimens get scaled along with the fonts. Another point is that the math symbol and extension fonts already have 22 or 13 fontdimens with a fixed meaning, so if you try to encode the math spacing in, say, fontdimen 23, TeX may incorrectly assume that there are valid values for the first 22 fontdimens, even if those weren't set. I'll have to see the actual code, I guess. Cheers, Ulrik.
