No suggestions, but this thread is a probably a good place to find nominees: https://bitcointalk.org/index.php?topic=5185736.0
The only name I recognise in post #1 is Ratimov who has started a Russian Language version of the Known Alts thread. (and Loycemobile who doesn't count - no offence LoyceV
)I haven't interacted with him practically at all, so am hesitant to nominate him without support/seconder.
