[Linux-HA] 3-node cluster using v1 config?

I'm thinking about setting up a 3-node linux-ha cluster, where
each 2 are set up as high-availability pairs for one service
(total of 3 services) and it can survive any one of the machines
going down.  Is it possible to do this with a v1-style configuration?
I'm thinking I can list all 3 nodes in every ha.cf but only list the 2
resources each machine cares about in haresources.  I'm dealing with a
higher-level script-based administration system (called CDB, at CERN)
that so far only knows about v1-style linux-ha configurations and so
I would rather avoid v2.  All 3 services for this case are actually
the same thing (load-balanced via round-robin DNS), so an alternative
I have is to reduce it to two more powerful machines instead of the
three I have now but that's a longer term plan.
