I wouldn't do that, and here's my reasoning:
You never empty all of the oil during a service. There is still 8-12 ounces of fluid left in the engine after you drain it, roughly 8 ounces in the primary, and about the same in the transmission.
Switching to a product that is closer to what you are going to run on a permanent basis will start thinning the old stuff out sooner.
Would it hurt to go cheap dino? Nah, not a bit.
