Could Voyager have made it home if Tuvix never got killed?

Let’s assume that Janeway never separated Tuvix and kept him as a crew member. Would the crew have still gotten home?

Assumptions:

• The subsequent story arc (and episode plots) are generally the same
• Any episode where the threat is caused by (or related to) the individual personalities of Neelix or Tuvok never happens
• Any episode where the day is saved by the individual personalities of Neelix or Tuvok is more dangerous
• We can assume that the strengths/weaknesses of Tuvix remain throughout the series

Do they still make it home? If not, what episodes are likely to end in disaster?
