Also, to my knowledge you'd be the first person to try this. Marpa has great tools for debugging your grammar, etc., but they are all at the higher (Perl) levels. So I would think it might be best to first develop using the Perl package, then convert.
If you want to know more, it's best to ask on the Marpa mailing list: marpa-parser@googlegroups.com There, other Marpa experts can participate.
