Cream Texture: Butter-like but Gel-smooth

Yes, combining Pro Polymer (an acrylate crosspolymer, which acts as a gelling agent/thickener) with Butter Cream Maker (an emulsifier designed for rich, buttery textures) is a suitable approach to create a cream with the texture you described – thick and heavy like butter, yet soft and smooth like a gel. Pro Polymer will contribute to the gel-like smoothness and thickness, while Butter Cream Maker will provide the buttery feel and emulsification needed for a stable cream. The exact ratio of these two ingredients will be crucial in achieving the desired balance between the "butter" and "gel" characteristics. You will likely need to experiment with different percentages of each to find the perfect texture.
