view inside a view with different arguments
I can't immediately think of a simple solution to this problem, but I also don't have VFV installed anywhere, so I can't play around with it at the moment.

What I would probably have done, is created a ctools content type, called both of the views, and manually rendered through a specific template afterwards. This solution however is non-trivial, so perhaps you will need to search for a different one.

See What are Ctools plugin (content type, access, etc), and how does one create them? for info on implementing ctools content types.
