Smooth seems like the logical choice because he is familiar with the CryptoNote codebase and has a proven willingness to look at other CryptoNote coins besides Monero.
The big question mark are his time availability and how much we can offer in terms of compensation
I have my hands full right now so I don't think I could do a good job on another coin at this point (and obviously the whole reason of bringing someone in would be someone with available time).
Also, I'm pretty sure that Zoidberg said he still wants BBR to be his main project, once he finishes his other work. I guess it is up to the community to decide whether to pursue another path, but that doesn't seem bad to me at all, unless he has changed his mind. He's obviously very capable and given that everything seems to be working fine the way it is I don't necessarily see any harm in waiting for him. Of course, if he changes his mind that's another story.
