Well, I'd have seven, so, that's at least seven things we could do!
I'd want at least one of them in armor. And if I had heavy armor fitted to me, I'd probably want to try it on, at which point we might as well have two suits of armor at which point we might as well have two of them armored up.
Personally, I think I'd feel ridiculous if I were wearing armor I couldn't easily cast in, but that's because I'd have to make the choice to put it on. She'd feel humiliated, which is a much sexier variety of embarrassment - at least, when it's happening to someone other than me. I'd want to knife her face up too, and maybe put her through the Gray Maiden training, although I'm worried that simulacra are hard to heal and also her Str score would not be very high. Unless I wished mine up and got a template before I made the simulacra and gave her a belt, maybe... at any rate, I'd want to break at least one of them down and turn her into my worshipful servant. Probably at least two, so I can have one who's a warrior-type and one who's domestic.
We could sing harmony, and play different instruments, and dress up in all kinds of outfits. And talk about books, or write books. You know, I used to want to write romance novels - I gave up the dream because it seemed too dangerous in Westcrown, and I'm too busy being a despot here, plus, Cheliax doesn't allow imports, so they'd never sell. But I'd enjoy reading them! It'd be great.
I'd want to put a helm of opposite alignment on one of them and see what I'm like as a Chaotic Good, and whether it's fun to make a CG Ileosa cry, and see how she gets along with you and Sabina.
I might feed one an elixir of sex shifting and force her to live as a man, although I'd have to be careful that she doesn't knock up any of household staff or Gray Maidens - that'd break rule nineteen.
