More semantics here....
An E-6 with warfare quals getting commissioned would be an LDO, not a WO. A WO would have to be a Chief first, which raises the question (in probably a majority of the cases), what happens to age maximums for starting flight training? I have seen my fair share of LDO's "the sh!t hot E-6s" and I can tell you with confidence that past performance is not necessarily indicative of future performance. Hell, I've seen my share of priors who picked up ECP and STA-21 who are also abysmall. I wish I still had the email I sent out that had farewell messages from a (literally) half-retarded SA and an ENS...the grammar was so bad in both that my family and friends couldn't tell who wrote which one.
Another semantics issue....carriers and their playmates are no longer battle groups, they are "strike groups" (CSG).
I digress, though. I agree that just about anyone can be taught to fly, and fly well. If the screening process rests too heavily on warfare quals for the enlisted, though, I see "failure" written all over it. Too many good people never get the chance to get ESWS or EAWS quals, and for others the process of getting that pin is far too easy.
All in all, I think giving flight hours to CWOs or LDOs by taking them away from guys who went through the USNA, ROTC, and OCS will only result in JOs dropping their letters at the first opportunity.
