Unfortunately, the Staff Roll tracks have already been taken by @Slimy as a part of his Ode to Star Fox remix. 'Come in Corneria' as you call it (or 'Game Clear Demonstration' as my source file calls it) has not been claimed, but now that I've submitted the project to OCR (even though I changed the tracklist one last time just after I did), I'm reluctant to change the tracklist any more than it already has been. I'd offer you the claim as a bonus track, but you already have Clipped Wings on the way!
That being said, I've considered adding a narrative element to the album after the last conversation we had regarding a 'radio play' approach to SCRAMBLE - we boiled it down to the vocals we have at the beginning, but I still think it's a cool idea. @YoshiBlade's Candy Corn album was a big inspiration to me in this regard; listening to that whole thing gave me buckets of ideas for possible future projects.
I'll consider this over the next couple of weeks. In the meantime, everyone: feel free to let me know what you think about this.

I've received @M_Blacki's Sector Y update, and he's now let me post to the WIP spreadsheet. He's gone with the SF64 version instead of the waltz from SF SNES - give it a listen and let us know what you think!
