If you are comfortable with complex perl structures you could make that 
work.  A day and a half might not be enough for me.  ;^)  You would
want to replace the old $Vend::Session or at least the cart with the new 
one as you are trying.  That gets into other issues: what sort of persistency?

How about the easy way out, writing the session variables you want to
some sort of frozen structure and then reading that in when you need
it?  That would not interfere with expiring sessions.  That might be something
like just loading an sql table with the items and then reading them out
on start of new session.  Key it on the session; then you could read that
prebuilt cart as often as you want.

It gets messy conceptually.  How long does the cart live?  Does it go away
when order?  Cookies?  How do you end the first session?
