Can I use I2C with an Uno as the master and a Lilypad as the slave?

I want to build a spider robot, with an Uno or Mega as a master, and with 4 Lilypads, each controlling a leg. Is it possible to use I2C with Lilypads, or should I use a different board?

Is it possible to use I2C with Lilypads

My first thought was sure, it's got the same 328 chip as the Uno. But, the I2C pins are not broken out, so no.

Why use 5 Arduinos to do what 1 can do?
