Philosophy is just not oriented to the outlook of someone who needs to resolve the issue, implement the corresponding solution, and then find out - possibly fatally - whether they got it right or wrong. Philosophy doesn't resolve things, it compiles positions and arguments. And if the debate about zombies is still considered open, then I'm sorry, but as Jeffreyssai says: Too slow!

Still, I hope your Friendliness structure can cope with the case where zombies are possible. Well, I guess that one wouldn't make any difference - so I should say I hope you're also trying to minimize the number of philosophical problems you have to be right about.
