I have a hunch that won't work and USE="udisks" is hard masked for gvfs.
Logic tells me that even if udisks:2 is available, gvfs won't use it.

But, it's worth a try.

I also think you need the maintainer to take a closer look - it all
looks like the ebuild needs some tweaking, or maybe it's just a magic
combination of USE that we missed.
