Is it possible to clone a Mac directly to another Mac with Carbon Copy Cloner, or with other means?

Is it possible to clone a Mac directly to another Mac with Carbon Copy Cloner? I just need an answer for macOS 10.13.6. Both machines have exactly the same hardware and OS, except that one of them is running with CPU Intel i7, the other with i9, and one has 512GB disk capacity and the other 256GB. Everything else, including the model A1990, and all other specs are the same. I am thinking of this so I can bypass the hassle of cloning to an external harddrive first and then restore to the 2nd Mac. I just need both Macbooks to be synced, so that if one is down for repair, there's practically no downtime. If CCCloner does not offer this, is there any other way to do this? P.S.: I am intending to always restrict my disk space usage to less than 256GB so I do not face problem of no disk space on the Mac that has lower disk capacity. P.S. No 2: I intend to do this syncing between machines on a regular basis (say once a day). Some have mentioned Migration Assistant. Is Migration Assistant suitable for such a frequent task?
