How to reuse a good IK rig with control bones in Armory?

After having made the rig of an Armature (using seperated meshes , then with bones : CTRL+P / Bones) in which IKs have been placed on some control bones/bones and which works perfectly well in Pose Mode, can one of these control bones be used from Armory while maintaining the perfect deformation obtained in Pose Mode ?

(I tested with nodes Bone IK and Bone FK not giving good results, adding transform or relationship constraints not functionning )
