Suppressing detail

So I am trying to create a toon character using the base genesis 3 maps as a starting point . What I want is some way to be able to suppresss all the unnecessary details alreasy present in the base skin . Is there some way I can do it without having to use something like photoshop(not too good at it)??

Could you just change the shader? These are both Genesis 8 Male. One with PW Toon.
Or here's applying PW Toon (White) but keeping the original surfaces.
pwtoon is a set of shaders for 3DL: https://www.daz3d.com/pwtoon
But these are only limited to 3DL right . That is not a small limitation for someone wanting to work primarily in iray.
True, but if you're going to do toon work, it may be better to consider 3dLight, the iRay renders really aren't as well designed for that type of work.
Then I would need to start learning how to work 3DL properly . That is definitely not what I want to invest so much time in.
Thank you for the help by the way.
This one is for iray: https://www.daz3d.com/sketchy-toon-edge-and-art-style-shaders-for-iray
It you want a true toon style than pwToon is what you want but if you want a claymation toon style (eg Pixar Toy Story) then you want the Sketchy product linked above.
