Studying this Entagma approach to recreating C4D's spline wrap deformer (very similar to XSI's Deform by Curve) in Houdini might provide some clues as to how to create something similar in Maya. I have no experience of creating custom tools for Maya but the Houdini custom tool approach might spark some inspiration for somebody more experienced in Maya's underlying wiring.
