Well the bureaucrat is inactive, so that's a "good" thing (well, for adoption purposes :P). The other admin seems to be inactive as well (technically it needs to be 60 days, but I don't know how lenient they are on that rule). No other truly active members either.
I'd say if you can keep editing for a while and that 1 admin doesn't come back, you'll have a good chance. If the admin does return, the wiki will still need a bureaucrat, so you can then discuss it with him (it is possible to have multiple people adopt a wiki). I'm no staff member though, so I can of course not give any "official" answers.
