One optimization, if you don't need the stored values, is to set
stored="false". Faceting is driven off the indexed terms, not the stored
values. But maybe you need the stored values (but maybe not).

Solr currently cannot do this automatically. But....
One thing that I built in to Solr Flare (long live Solr Flare!) was a startup
request to Solr's luke request handler (/admin/luke?numTerms=0) and got the
list of field names. Then, and I used *_facet similar to you, kept a list of
all *_facet actual field names and used those in all subsequent search requests.
