You should attempt to advertise the /21 at each site along with the 
site's /22

If you dont have dedicated interconnectivity between the sites, 
tunneling *carefully* should do the trick.

This will ensure that if/when those who filter on strict allocation 
boundaries dont hear your /22, there will still be reachability, even if 
suboptimal, to your sites.
