"-Try to put together a Silo-Poser or Silo- solution?"

Silo is a stripped down modeler. by trying to use it as a renderer - for POSER content creation - you are entirely missing the point.

you said you want to create content for Poser. why wouldnt you just render in Poser?  as i have already pointed out, there are some extra considerations when modeling to ensure that things look good rendered in the Poser renderer. if you are creating for Poser you should be rendering in Poser - not Max, or C4D, or Modo, or Silo with some POV ray export. part of the reason there is so much bad feedback on props and sets created by non-Poser users in Max, LW, etc and submitted to the marketplace is that people encounter all sortsof issues once the object is imported and render in Poser.

 

"This forum helped me boil down to just these 3 options"

you are missing the most straightforward option:
model in Silo, render in the target application (Poser).

 

if you want a modeling suite with a solid renderer and all the bells and whistles, then buy C4D.
