Hi resort-sand,
Thanks for the files, and for using WeTransfer.
To get it smaller and smaller requires that the Length and the height of the words shrink equally. Which would also move them. This is not an option with MoGraph.
My suggestion would be to solve this with 3D and perspective.

The setup has a little "cheat" with a Taper Deformer to improve the flow.

To see the full text, it needs to be rendered. The small text on the end requires at least a 16K render, I assume more.
The setup is a balance of camera distance, the field of view, and the Length of the Helix. The light on the camera has no falloff!
My best wishes for the project
