[Blender] Making normal texture map out of base texture map?

[Lonecat Nekophrodite]

Is it possible? and how?

This is what i've achieved today. adding wood textures onto this model

This wood texture comes with Normal map version. ... Is it possible to make one using existing base UV texture map to the left? I don't want to align normal map of the wood texture onto base map one. if so how and is it possible with Photoshop? or other tools??
