Help me build my Goblin Synth Summoner

I am working on a character for an ongoing champain.
Level 10
20 point buy
30,000gp worth of gear
All Pathfinder books avalable

Was thinking along the lines of Stich on crack. Little guy is obsessed with mythical goblin heroes of old who used huge weapons and were as tall as giants.

Biped base form, Large and Weapon Proficiency Evolutions, and get yourself a Large sized weapon.

Say the eidolon looks like a big goblin, and you've got a mythical goblin hero of old who is as tall as a giant, using a large weapon at least.

Upgrade when Huge becomes available :P
