In general conformal mesh between two parts (share topology on) is the best way to connect two bodies if they are supposed to be tightly connected and not have relative movement wrt each other. You can try insert different mesh controls, eg. separate size controls on each body, different mesh method, mesh the parts in different sequence etc. If this doesn't help, you can use the bonded contact definition like you mentioned. Usually bonded contact shouldn't add much convergence difficulties since it is linear contact. You might need to take a closer look at the warning/error messages. Did it show the bonded contact is successfully connected? From the figure it is not very clear how you define the contact, is it face-face or edge-face? If the later you might want to switch to MPC formulation. n
