In that case, if you have the knowledge and feel like it's worth it, start debugging to find out what kind of interference the plugins have. You might also try to use Google and see if there are general recommendations or even a known interference of those plugins.
However, the more I think about it, the less I think the closure trap will work. I don't think either plugin just registers global variables that interfere, but instead they define objects attached to jQuery which interfere. Now you could change at least one of the plugins to adapt it to a different object, but that would most likely break the plugin as it cannot use jQuery functions anymore.
In that case, and if you can't find anything on Google, the way to go would be deactivating one plugin. Either the one you only need on one page (hurts less) or the one you might be able to find a different plugin for or even write yourself.
