The crank spindle is only so long, and may not have enough adjustment. Do you have any spacers on the non drive side? Some chainrings also have more offset than others, so it can depend on the chainring manufacturer. Either way, pushing the chainring out will likely result in crappy shifting and premature component wear.
What freehub is on your wheelset? If you have an XD freehub driver, you may be better off getting one of the cassettes with a 9 tooth cog, eThirteen makes a few versions. That combined with your existing chainring woukd probably give you enough top end.
