The near/far clip planes for the projection matrix can be redefined(unique) for each draw-call/model which gives better shadow mapping precision & allows decals to be so close to the surface of models that silhouette issues vanish.

I assume that you’re asking whether this is possible.
The short answer is “no, not really,” because the near/far clip planes also determine depth buffer testing. When you draw a scene, and then draw a character in that scene, you need to use the same near/far clip plane for shadows to match up, and for characters/geometry to not weirdly intersect each other.
If you want to render a composite scene, where only self-shadowing matters (there’s no object/object scene interactions) then you can accomplish this with a render target and an offscreen render target camera per character; you can set the near/far clip plane for each separate render you issue this way.
