Hey, thank you for suggestions!
These are cool ideas, willful deformations of Sipho could add a lot of undiscovered synergy between parts.
Talking about existing parts, we designed them with idea that each could do it's own job and be inherently useful without any other part. That keeps complexity low and helps to learn the game and does not require additional step of finding another part that might make another useful. Bonus/emergent synergies between parts are also our goal when designing one.
Since we had base zooids for breeds in place, we have allowed ourselves to make wackier parts, like grappling hook or energy leech. So we might experiment with things like you suggested.
