Rene, IIUC, you are /not/ using VDSM at the moment. Is this right? If so, than you should probably add one host at a time, and after the first 1-2 hosts you should import the VM's into the Engine.
However, if you /are/ using vsdm, then it is possible to add a host without going through the whole bootstrap process. Note that using this features, makes you responsibly for everything to be up & running for the engine-core to work with. This can be achieved by setting the InstallVds entry to false using engin-config.
