It would be up to the staff there especially as you are on 2 separate tickets but no harm in asking.
Remember that whilst VS an DL have a Joint Venture VS isn't a member of skyteam so any skyteam benefits you might have won't necessarily flow through and that would include bags being interlined.
Many airlines now refuse to interline on separate tickets unless both airlines are part of the same alliance.
