Some versions of BIND would allow you to do this (some only if you specified the multiple-cnames yes option) and would round-robin load-balance between then but it's not technically legal. There are not supposed to be resource records (RRs) with the same name as a CNAME and, to pick nits, that would include multiple identical CNAMEs.
