I think you could, but with what 11-KT can do on its own, I would opt to save it for PCT, as well.
And regarding stacking topical with AMMO, you can, but I wouldn't personally dose AMMO both in AM and PM; just one or the other and topical only once.
I also never run AMMO more than 2 bottles in a row without a month off, but actually prefer 1 month on/off since I have Absolutely Abliderated to use in the off time anyway.
