Lots of people have invented non-XML syntaxes for XSLT; they have all died a quiet death without achieving any signfiicant adoption.
I think there are a number of reasons:
(a) the use of XML syntax is off-putting to beginners but no problem at all to experienced users
(b) using a preprocessor makes development a lot more complicated - diagnostics are less helpful, and helpful diagnostics are much more important to developers than pretty syntax.
