Would it be possible to please make a version for Babric/Minecraft Beta 1.7.3?

There is a version for Ornithe b1.7.3 (though I just realized it hasn't been updated to AC 1.9 yet). I may consider porting that over to Babric at some point, but Babric will start using Ornithe's gen2 intermediary in the near future, and then you'll be able to use the Ornithe release on Babric.
