I should point out that the adoption help page mentions:
"The community that you want to adopt needs its former administrator(s) to have been inactive for at least 60 days; you can check this by going to Special:ListAdmins. There can be exceptions to this in certain cases, but generally, this rule is followed. You can adopt no more than one community per month."
It would not hurt to put in an adoption request and explaining why this isn't a regular case, seeing how you have nothing to lose by trying.
