Midfilm wouldn't work - then it wouldn't be much of a climatic end, would it? Perhaps the T. rex replacement should wait until the fifth installment, or the replacement could serve a role as secondary antagonist, and at the very end it could be seen feeding on the corpses of the T. rex and Spinosaurus and roars ominously and then plays a major role in #5. Yes, I think Carnotaurus or Quetzalcoatlis/Hatzegopteryx could make a really good secondary villain for JPIV.
