I think a Chipco (or ceramic) would be hard to emulate in something like Chip Forge because of all of the near limitless customizations avaliabe to ceramic chips ... there's no set anything on a ceramic like there is with clays (i.e. the mold, edge spot patterns, inlay sizes, etc.), people are better off doing that stuff in Illustrator (or similar vector program), or Photoshop (or similar image editing program).
Honestly all you need for a mockup is a graphic program that will make circle and you're set.
To emulate a chipco make one circle, then a second circle almost as large (to simulate the outer white ring).
For a BR Pro all you'd need is a circle, as you can use the entire chip.
The only problem you may run into is for the NJ's. I don't know much about them to be honest but they all seem to have some kind of variant of stock borders. Someone more familiar with their ordering process can set you straight i'm sure.
