You can use LiftRules.statelessRewrite which is processed very early before the SiteMap comes into the picture. Hence you can rewrite at this level. LiftRules.statefulRewrite is processed a little later on (but you have full S context) but still before SiteMap is processed.
If this doesn't fit your needs, using your approach is not bad either. Not sure where the boilerplate is as RESTfulLoc looks like a generic one.
