Hi Mike, it looks like you've got some good tips on how to proceed.

But just a general note - usually things that have a lot of little lumps and bumps in them tend to be more in the domain of a sub-division surface polygon modeling program and not so much in the area of a CAD type program.

MoI does have some various freeform surface creation tools which may work for what you are describing, but really a polygon modeler is much more focused on making those kinds of free sculpted lumpy type models.
