Gotcha, thanks for the further explanation! I'll discuss this with my co-mod (though I believe she's also canonblind) before giving a final answer. Generally, a player character's world encroaching on/merging with the Barge is nixed (outside of big player plot events), but if there's precedent for him being able to use these powers while completely removed from the Metaverse, that might be a bit more doable!
