I wonder if it is possible to take it one step further and render generated MathML expressions (or more accurate to say the corresponding images) instead of «HTML math»?
As far as I understand your main concern is math accessibility issues, so my suggestion is probably not in line with your primary interests. That being said, it is rather dubious pleasure to read an article with two types of math glyphs. I trust, some people would appreciate unified look for formulae. I can easily be wrong, but I am under impression that you have already done most of the work needed to implement the proposed functionality (again it is just my guess), so you might want to give it a consideration.
