Redoing Summoning

Well i would like all of your help.

I would like to change the three types of summoning spells in my game to something like the astral construct of psionics. I want to start with a base creature and allow the summoner to add parts off menus to make various creature types. I need some input on the type of powers each of the menus should offer. so far i got:

So i need 10 choices for levels 1-3
undead
Nature
Monster

Each should have different choices

For undead am thinking

Bones: Grants 5/blunt
Flesh(Zombie): Grants 5 slashing
Silent: makes no noise when moving
Claws: Increases base damage
Incorporeal
Attack causes Paralysis
Attack causes disease
cause fear
reknit form( Fast heal 1)


For nature would be

Extra attacks(claw/claw/bite)
Wings
Climb
Burrow
Pounce
Improved Trip
Improved Grab
Swim
Increase natural damage

Monsters.... not sure.

So any help with getting the first menu done at least (Menu A) then i can work on the higher level ones.
