The scenario of manually connecting the hosted-engine host to several paths
wasn't tested before, but by theory it should work.
As you said, the host should be set to global maintenance, disconnected
from the single iSCSI session [1] and reconnected to the dual paths [2].
Then host re-activation.

[1]  # iscsiadm -m session -u
     # iscsiadm -m node -o delete
[2] # iscsiadm -m discovery -t sendtargets -p target_IP:port
    # iscsiadm -m node target_name -l
