There is a fair bit of voodoo involved in getting these things right. keep experimenting but careful what you do with the results.

I'd try and remove any fixed connections to the rock. You may have to reduce the interface to a line to do it.

Failure will not occur with a peak stress at yield. You can safely let it go up to the material ultimate stress.

Have you actually modelled the pin or have you just got 4 independant analyses of the lobes?

The more powerful the package you use, the harder it is to learn it. So stick with something simple. The combined CAD/FEA you have is the way to go for a project like this. Have fun and careful with your units.

PS. FEA and manufacturability are completely unrelated. :)
