Hm, I definitely agree with this, especially the bit about the icons by Robin's health % since that would give the player a visual indication on what they're dealing with for management purposes rather than having to be oblivious. Mac having an indicator for the KO Punch and the emphasis aiding Olimar's strategies for Pikmin management make me me believe that this will be the case.I think Robin will just have four little icons by her health %. As you spam a specific special, it starts to drain a resource and the corresponding icon for that element will begin to flicker as it gets low. If you run out of juice, the tome fizzles out and the icon is discoloured for a while, signifying it's no longer available. After a short time period, it will regenerate.
I think the Bronze Sword levels up to a Levin Sword just by dealing spell damage, and levels down to a Bronze Sword after dealing a certain amount of physical damage. So the ideal play style is you rack up damage with careful spell management, and go in for the kill with your empowered Levin Sword.
Mind if I add your thoughts to the list of theories?
