Absolutely. The first step, after getting comfortable with the Apocalypses and Exegeses is to head over to perl6-internals list and poke around some. As people show up and have time, we'll make sure everyone's reasonably coordinated.

The whole task is pretty straightforward--perl 6 goes in, parrot bytecode comes out. That doesn't mean we have to take it in one go, as there are enough intermediate steps to go around.

It's probably also worth taking a mild shot at it by yourself to start, with the knowledge that you'll throw it all away and keep only the experience from it. (Which isn't a bad thing at all--get used to throwing code away, it makes life a lot easier in the long run)
