I do not think it is realistic. It may require models for various 
natural languages and for math expressions. It would be necessary to 
carefully track modifications of text to avoid performance degradation.

Example of false positive:

Till somebody will demonstrate reliable recognition of "$n$th" you may 
use zero-width space after "$" and an export filter that removes these 
separators.

Personally, I would prefer more strict syntax to avoid zero width spaces 
even if it will require more verbose markup.
