I'd be interested, but I've never played 5e. I've just been browsing what's available online because a buddy of mine plays it and I'd like to be able to jump in some time. As for themes, I think the best ones don't dictate the mechanics; for instance, if you wanted to do "nature," then druids, scouts, barbarians, or rangers could fit. I'm not suggesting nature, I'm just saying I'd rather have a theme that could lend itself to a martial mundane or a full caster equally.
