Permanent Minionmancy in Pathfinder?

[g3taso]

What if I spent one fine morning
1) Casting Polymorph on an encountered monster (any type, but let's say a conquered boss-type critter with lots of class levels for example) to turn them into a wiener dog. Spell source http://www.d20pfsrd.com/magic/all-spells/p/polymorph
2. Casting Pup Shape on that critter, which neatly overrides the dog form and leaves you with a 1HD child creature of some type and completely unable to resist you. Spell source http://paizo.com/pathfinderRPG/prd/ultimateCombat/spells/pupShape.html
3. Mindrape/Programmed Amnesia the heck out of that child creature and make yourself a completely devoted servant while still in child form. Spell source http://dndtools.pw/spells/book-of-vile-darkness--37/mindrape--165/
4. Use this "perfect vessel" and make him an absolutely loyal undead minion that doesn't have to be controlled, because he is a willing vessel.

note #4 is optional. there are perfectly good reasons to have living, breathing beings who live to serve you, who's reason for existence is a smile from their master.

1. Per Pfsrd: "You can only be affected by one polymorph spell at a time. If a new polymorph spell is cast on you (or you activate a polymorph effect, such as wild shape), you can decide whether or not to allow it to affect you, taking the place of the old spell. In addition, other spells that change your size have no effect on you while you are under the effects of a polymorph spell." You can't hit something under Polymorph with Pup Shape. They are both polymorph spells.

2. Why bother? If you can make them fail a will save for polymorph, you can make them fail a more difficult will save for mindrape without the intermediate spells.

Also mindrape is 3.5 not pathfinder... frankly it IS just easier to hit them with mindrape in the first part. Or planar bind some creatures in and mind rape them.
