Reach, stacking reach and larger weapons?

Depending on the feat, yeah. Inhuman Reach would work, but I seem to recall that Deformity (Tall) just plays around with size.

Inhuman Reach and Deformity Tall each add +5 ft of reach. The fluff text on Deformity Tall talks about how you're unnaturally tall, but you explicitly stay the same size.
