I rather suggest to multiply `ascender - descender' by a given value;
for example, TeX uses the factor 1.2 by default.  Otherwise, the lines
are sticking.

I'm not exactly sure what you want, but what about the value

  1.2 * (ascender - descender) - (ascender - descender)

     = 0.2 * (ascender - descender)
