Yes, I have already worked with Linux-HA and I had planned on using it
for this setup.

Sure, that would also be possible. But I want to know if there are any
drawbacks wrt starting up one nagios process on one node with the
retention data that was kept up-to-date by the other node.

In other words: if you could put the nagios state data on some storage that
is not a SPOF, would there still be a compelling reason to use some NSCA-like
replication from one Nagios process to the other ?
