I favour multi-legged variants. I'm thinking of a six-legged beetle-like model, that in small varieties can be used as a bulk cargo mechs with cargo space under the 'carapace' armour (which even opens that way to allow access for loading/unloading, engine and defense options in the thorax and cockpit/crew quarters in the head. It could even be scaled up small City-Mech size, a really large beetle. Any good book on insects has loads of inspiration, BombardierBeetle anyone?

Spiders should work too, remember that Mech in 'WildWildWest'....
