Dire actually welcomes dialogs with mod devs. Though I think hopping into the TS that he's using would probably be your best bet. I'm betting his inbox on MCF is completely useless, and he probably gets spammed to Antarctica and back on IRC too. Very reasonable/congenial fellow, and letting him know that v7 is coming out here soon which would be the PERFECT time to release a spotlight would help. He only does spotlights when the mod author wants them, he realizes how important the presentation is, and actively encourages mod authors to have a reasonably completed/finished/stable product before he does spotlights. Which your release schedule is perfect for, incidentally
.
That opinion is based on his comments across a very wide swath of videos. I've watched literally everything the man has produced other than his Aureylian stuff (Something about her just trips my GTFO sensor, I can't watch any of her content and it mystifies me as to why), charity streams, mod spotlights, and his 3 most recent "let's play ____ with ____" (Which I'm working on), so that's a VERY large sample size.
Plus he HAS offered a spotlight before, so simply maintaining a friendly dialog with Dire would probably go a long way towards him working you into his schedule by simple expedient of you (and your mods) being kept in the foreground of his mind, like the mods he normally plays with.
