I just scribbled this up quickly and took a picture. Obviously, only the NO (normally open) and COM (common) pins would be used in this case, with double-pole relays.

Is this what you mean?

Here, I scribbled up a slightly different version. This one is idiot-proof. It uses the normally-closed contacts of each relay to prevent the other relay from engaging at the same time. If you have two sets of trim switches, this circuit will give priority to whichever switch is pressed first, so in the event that "up" and "down" are hit at the same time, it won't cause a short condition.

Like the other circuit, this will give 24 volt UP trim and 12 volt DOWN trim. Is this what you wanted?

Well I guess I wasted my time writing that response. No good?
