yes, it is possible to support KaTeX. Try the following configuration file:

------------
\Preamble{xhtml,mathjax}
\Configure{MathjaxSource}{}

There is one downside: KaTeX supports even less LaTeX commands than
MathJax, not mentioning all custom commands you use in your documents.
So I can predict that you will have lot of troubles in trying to write
