Back-up character ideas

I wanted to list my backup characters I have either created or will be creating soon.  No matter what we want to keep a well rounded group.  Please feel free to post your back-ups as well.

Summoner - No archtype.  While he will have a pretty powerful Eidolon, he will more than likely focus on sending out his SLA summons.  They are standard actions to cast and last for 1 minute per level.  When he brings out his Eidolon it will be via second level spell.  Will use his spells to buff his eidolon and others for control.  he will get teloport but not rope trick.

Shaman - this is the spontanious druid I have.  He will wild shape into an elemental.  He will be blaster / back-up healer/secondary fighter. This would leave the group hurting for Haste, teleport and rope trick.

Enforcer - My gun dude.

Sorcerer - not fleshed out yet. Will be different than the wizard.  Maybe a duel blooded human?

White necromancer - not published yet but high on my to play list. Wizard varient I believe.

I'd like to stick to the same role: tank.

Palladin

Tank Druid: use wild shape and animal companion to be the tank. May not work too well if other PCs have companions.

Summoner: use the eidelon as the tank.

Sorcerer/Dragon Disciple: probably be very weak tank...

When I purchase the pdf of the battle scion class, I will let you see it as well (arcane paladin.)

So far i have:

Grax- houndmaster with puppies tank -only if the others all manage to die

Tower shield fighter- Svirfneblin tank fighter about same damage output as monk on single target will probably have standstill tree if possibly dex based very high ac.

Eagle shaman druid- will spend most of the time shapeshifted using natural spell feat to cast and maybe summon a swarm of eagles on big bosses high damage striker but low ac

Archer fighter- long range striker

Oracle of heaven- backup healer along with controller

Shield and board spell-less ranger- tank with a companion to help with flanks and such.

Two-handed fighter-melee striker dead

Thesleeper -rogue that really really likes to smash things and heads :)this guy --->

If my friend Scott plays, he will play a Ranger/Archer type.

My backup is a rogue/wizard, headed for Arcane Archer.
