I was working with an idea a while back that I never quite finished. Instead of coming up with a wall of text in details of what it should be like, I figured maybe it was worth dicussing first. Here is my suggestion:
If you would be able to "lock" your items before you left your mog house, you would recieve a bonus. It could be "Haste+20%", "Magic attack+ 20%", "Double attack+20%" etc. This would stop the need of swapping gear constantly and and free up macro space.
If you like my suggestion, please post some of your ideas for a bonus^_-
