Well...a SLI mobo with a single slot in between the two PCIe video slots should work using an SLI connector from any company that uses a similar configuration. And a SLI connector built for a mobo that has the two PCIe slots next to each other should work with any other mobo that uses a similar configuration. After all, the positions of the slots have to correspond with ATX specifications so you can access them in standard ATX cases. I do think that a flexible SLI bridge is a much better implementation than the ones using a rigid pcb for various reasons. The flexible bridge I linked to from Monarch Computer should work as I'm sure they designed it with headroom to spare. If you're not sure, measure the distance between the two PCIe slots in your mobo and give Monarch a call/email to see how long the flexible SLI bridge they sell is.
