As far as the "new" innocence, who knows exactly how it will work. For the parasyte types we were shown: Allen had his from birth, and Crow-kun's were already in the shape of teeth when they entered his body via a carniviorus plant. Lenalee's didn't really look like anything short of a bunch of dust to me once she took the innocence off. For all we know, there needs to be a mold of what the person needs/wants when the innocence is first introduced as a parasyte type. In this case, perhaps Lenalee will end up with just boots, something weird (for her) like a sword, M-16, or boxing gloves (I really can't see any of these with Lenalee), or perhaps even a new outfit/armour thing that would include boots, gauntlets of some form, and body armour or helmet of some type.
