If you're interested in some totally-out-of-left-field crossover material for Dimitri, why not try Allura from Voltron? She absolutely looks like she could be from Duscur, she's a super-strong space elf, and she's the paladin of the Blue Lion. It could be a lot of fun to dump her into a Fódlan setting and I have some ideas for how that could work, to set things up.
