"If condition A happens, then do option 1; as of condition B, do option 2."?

You could have answered this question yourself simply by looking in a dictionary.

So (as already indicated in some comments and in your question) as of is used to indicate the commencement date of a 'situation': it is not used in the way proposed in your question; so, yes, it is grammatically wrong.
As also already mentioned in the comments, the correct terminology would be:
"as for condition B".
