All it would be nice to have Ptex capability within Blender. If this is not already something which is being considered or such I can spin up a project to design and implement within blender. If this is already a project or on the radar then I can assist.

For those who would like to know more about Ptex I have included the link. In short Ptex is a Walt Disney technique for using seamless textures without UV unwrapping. This is being implemented by many 3D packages and Renderers since Disney has made this open source.
