I think it's not a good idea.
(1) You have to use a different syntax. Such changes are always
bad.
(2) groff can't handle, say, right-to-left languages at all. It
is software which is basically more than 30 years old. While
groff could be extended to handle this (and there are roff
versions which can do this), it's unlike that it gets ever
implemented.
It's not clear to me why you get such bad formatting results. IMHO,
it's not a problem of the syntax (neither groff nor TeX do much more)
but rather a bad conversion from Wiki syntax to the printer output.
