More than one rig for the same character

I am trying to make a dragon with multiple rigs i have made in blender. My idea is to have it able to land on and grab hold of buildings and towers, so i figured i would try implementing some IK animations. I have gotten the impression that this would be easiest if I use a humanoid rig in mechanim.

The rig i made in blender kindof fits the dragon, and it is imported as a humanoid just fine. But I would like to add a tail and a couple of wings aswell, but their animations do not deform the mesh.

Is it possible to have more than one rig on a humanoid character?

Should i instead make a generic rig and try looking into IKs for that?

I had a similar issue with a few of the characters I created. If the animation works in blender, i.e. the tail and wings work properly all you need to do is activate those bones in Unity. Keep your rig as a humanoid and enable the transform bones inside each of the animations under the animations tab in the inspector or add extra transform to expose underneath the rig.
