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

------------
\Preamble{xhtml,mathjax}
\Configure{MathjaxSource}{}
\Configure{@HEAD}{\HCode{
<link rel="stylesheet"
href="https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.min.css"

}}
\begin{document}
\EndPreamble

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
a support for your documents.
I am not sure it is worth the trouble, but you will see.
