Active/Active to 2x Active/Passive?

I have a 2-node active/active cluster (SQL2KSP4 on Win2003sp1)
supporting 3 instances (2 on one node, 1 on the other). I've received
funding to upgrade the instances by adding new host nodes with
better/faster hardware (Yay!).
The end-result should be the 3 instances running active on the two new
hosts (2 on one, 1 on the other, just like before), with each new host
failing to an old host. Due to SQL licensing, I know I can't run active
on more than 2 hosts; the third instance has very little load/activity,
so I'm not concerned there.
The questions are many:
1) can I accomplish this while keeping everything within the one windows
cluster, or must I break it into two distinct clusters?
2) If I have to break it into two clusters, can I rename the existing
cluster so that the old and new clusters (and their nodes) can fit a
naming convention?
2a) Is possible to evict a node from a cluster, then bring it up as a
different cluster (1-node) without re-installing SQL2K for each instance?
3) Is there any way to pre-install SQL2K on the cluster node that's
being added to eliminate downtime?
Any pointers or tips would be greatly appreciated!
If I understand you correctly, you can accomplish it with a four-node cluster.
