Here are both of my coppers.

The archetypes could be:

Naturalist:

The Summoner gets Summon Nature ally instead of Summon Monster, which is a really raw deal, isn't it? But don't worry, it'll get better.

Lesser : When you summon a critter, they automatically get magic fang cast on them

Medium : When you summon a critter, they get something neat.

Greater : When you summon just one critter, get to be greenbound. If you summon multiple with the option to summon multiple of a lower level, they instead get an extra +4 str on top of the augment critter feat.

Your companion is instead an animal companion you summon, and gets to be dire for free at some point.

Minionmancer :

You summon lots of little dudes. Whenever you summon multiple dudes, you get an extra dude.

Lesser: You get 1 extra dude.

Medium: You get two extra dudes, and your dudes are flanking any baddie that more than one of them are adjacent to.

Greater: You get 4 extra dudes!

Companion is a regular dude, but you get two of them.

Elements :

You don't summon boring dudes, you summon elemental dudes!

You can only summon elementals, which sucks, but you can expand two summons to get a dude of one higher level summon, ad you have 1.5* as many summons.

Lesser: Your summons get at will spells!

Medium: Your summons get better at will spells!

Greater: Your summons get even better at will spells, and each summon has a once per summon special power! Neat!

Companion: Your companion is any regular dude with a half- elemental template. It can change when you summon it.

Necrosummoner:

You summon dead dudes.

You summon undead.

Lesser: You get a neat feat for when you summon undead. Plus, your undead get extra HP based on your cha.

Medium: You also can rebuke dead dudes!

Greater: You get to be a dead dude! Maybe a vampire? Lich is probably too strong.

Your companion is an undead dude.


Now someone make that... less dudey.
