Just an update/FYI I actually did figure this out after reading another comment of yours! My logic was flawed in the assumption that we only wanted the register's load bit to be 1 when we load from "in". I hope this isn't too much of a hint to others looking to solve this the "simple way" but we actually want the register's load bit to be true any time there is an operation requiring a state change in the register. From there it was a simple matter of combinational logic to construct what constitutes a state change - and voila!

I read many other posts with people who came up with all kinds of interesting and (sometimes overly) complex solutions. Glad to report that it is in fact possible to take the straightforward approach with this one!
