Ok, have a workstation whose monitors are normally configured like this:
2 video cards, one feeding monitor  and the other doing . Pretty standard and windows XP can multimon, do it every day.
But now we have a request for the following:
But the rub is we need to clone/mirror 2 onto 4 and 3 onto 5. This is for a classroom so the students can see the images from 2 and 3 without crowding. Of course  and  are larger format monitors which can support different resolutions than and.
We've used DVI splitters, and encountered issues with splitters failing, video glitching on the primary monitors , and EDID issues - pulling pin7 on the DVI cable helped with EDID but I'd prefer NOT to have to modify cables.
I've been looking for a way to do it (XP, but moving toward 7) in software by adding another video card to drive , even if it takes add-on software to do it.

One option would be to use a total of 3 video cards, with 2 and 4 connected to one dual card and 3 and 5 to the other. Then set both video cards to use clone mode.
If the system doesn't have 3 x16 PCIe slots you could get an x1 video card such as the Nvidia Quadro NVS 300 as the 3rd video card.
A possible software solution would be the MirrorMon add-on for UltraMon, but you should test if performance is sufficient for your needs. MirrorMon can be configured via command line arguments so you could launch both instances from a single batch file or script.
