Yes, you can achieve this in Spine by using skin constraints. Skin constraints allow you to apply different constraints to bones based on the active skin. This means you can have a specific constraint for the AquaSuit pipe that is only active when the "AquaSkin" is applied. You can set up these constraints in the Spine Editor, ensuring that they are only active for the specific skin you want. This way, your character can have different physics behaviors depending on the skin that is active.
For more detailed guidance, you can refer to the Spine User Guide on Skin Constraints and the blog post on Skin Constraints for Different Proportions.
