Tyranid and Necron leaders in campaigns

Since these fleets don't have admirals how do you handle appeals and renown for them?

The Necron fleet was written before the retcon-pocalypse that killed the C'tan and made the Necrons more independent.  I think I saw another fleet list out there, but in lieu of that, I'd just use the Imperial Navy tables, obviously without letting the Necrons have access to the Space Marine table (that would be silly).

As for Tyranids, they don't have leaders at all, and are quite hard to shoehorn into campaigns.  However, I've written some homebrew rules to take care of this:

Thanks, I figured I'd have to bodge this but just wanted to make sure there was nothing official.
