And considering "Ecliptic Umbrae" would've involved the Karjamian Mythos (PK and Nega-Lime), that's likely non-canon too, but YMMV.
I'll ask Kim about it. I mean, in Apocalyptic Shadow, Amy van der Skyff is a game developer who created "Into the Unknown", so maybe DR could be similar? :p
... Awful lot of things I've gotta ask her today. This, the sockmins, if she'd be okay with getting gloves for Christmas (in summer, since the southern hemisphere's now in summer)...
The Qoutev material regarding those characters is public domain so PK and Nega Lime could still appear in Ecliptic Umbrae. Oh and it's actually neat that Apocalyptic Shadow references one of your old mods. I suppose Dragon Riders could be fictional in the Lunar Shadow universe and vice versa.
