A good percentage of this routine just reloads the upper immediate, obviously wasting space. A simple rewrite to save space could be nice. A loop would save a little more space but you would be more restricted to what items you can add since there simply is not enough room to create a table to include all the items. So 42a74 - 42AAF freed up rather easily, add more starting items or just use the space for something else. Also to note r4 and maybe r5 should be free registers.
