I took a quick look at the code and really don't see any attempt to resolve sysvars in the collection create code so I don't think this is supported. Certainly sysvar substitution when reading core.properties files is supported.
I don't know what gotchas there'd be in supporting this, you could raise a JIRA to discuss it if you'd like (even better provide a patch).
