You can for sure pull the engine, leaving the tranny in place, but in my experience it's going to be a lot harder to get the new engine & old tranny aligned and done right that way. It's LOTS easier to pull the engine & tranny, connect the new engine & tranny on the shop floor, and re-install the engine & tranny as a unit. Others may disagree.
