Hmmm. There has been quite a bit of work lately to support a couple of things that might be of interest (4.3, which Simon cut today, probably available to all mid next week at the latest). Basically, you can choose to pre-define all the cores in solr.xml (so-called "old style") _or_ use the new-style solr.xml which uses "auto-discover" mode to walk the indicated directory and find all the cores (indicated by the presence of a 'core.properties' file). Don't know if this would make your particular case easier, and I should warn you that this is relatively new code (although there are some reasonable unit tests).
You also have the option to only load the cores when they are referenced, and only keep N cores open at a time (loadOnStartup and transient properties). See: http://wiki.apache.org/solr/CoreAdmin#Configuration and http://wiki.apache.org/solr/Solr.xml%204.3%20and%20beyond Note, the docs are somewhat sketchy, so if you try to go down this route let us know anything that should be improved (or you can be added to the list of wiki page contributors and help out!)
