I believe that there's a configuration option that'll make on-deck searchers be used if they're needed even if they're not fully warmed yet. You might try that option and see if it doesn't solve your 503 errors.
I'm fairly sure that this option (useColdSearcher) only applies to warming queries defined in solrconfig.xml, and that it only applies to situations when the searcher that is warming up is the *ONLY* searcher that exists. The only time that should happen is at Solr startup and core reload. At that time, the only warming queries that will be executed are those configured for the firstSearcher event.
A quick peek at the code (branch_4x, SolrCore.java, starting at line 1647) seems to confirm this. I did not do an in-depth analysis.
