You're not actually supposed to do that.

Interwiki transclusion is very server intensive, so when it's used specifically for signatures, it is required that you subst: the template with. I think that's the correct format.

Unfortunately, then you're between a rock and a hard place because this doesn't help the problem of 2-3 line signatures. =\
