You can try mount the server file system remotely on the others computes, but it probably will lead to a error because more than one instance of bitcoin is running (the core knows it because the .lock file). 
But if your node are already running, there is no reason to have more then one node running, just download a SPV, as you can see above(electrum are a good one), and connect it to your full node. You not will loose privacy in this case
