Thanks for the files, Kevin!
Here is the simplest version that I can think of. It allows for painting on every single clone a MoGraph Weigh to define how randomly you like to have on each, while the setup has only a few parts.
The idea was to take the “profile” with the 11 elements and create a Spline via MG-Tracer. Then produce an object, and use that as a “matrix”.
The adjustability is certainly given. Although the Loft can be invisible, I left it on to showcase the idea.
File: (I did not use any original part of your file, so I hope it is OK to share it.)
All the best
