We don't move things to beta, its just not how its done. [This post][1] states the reasoning behind it. *If* SR.SE makes it past beta, chances are not all questions you might want to move would make the quality criteria in any case. 

That said, if I saw questions that are unwanted here, but would make a great fit there, SR.SE was out of beta, and I'd talked to the relevant mods I'd probably end up flagging it for migration, rather than relying on VTMing
