I doubt you'll see that soon. I'd imagine they won't want the extra work maintaining too many wallets.
Since AEON's goal is to be mobile friendly and is "partnered" with Monero, a nice feature of any future AEON mobile (or desktop) wallet might be to pay recipients in Monero. i.e. Implementing something like xmr.to or shapeshift.io from within the wallet. AEON -> XMR. That would probably help adoption.
AEON could always provide some redundancy for those sites (Mastercard to XMR's Visa) in case something happened with XMR. The extra effort adding another cryptonote coin surely wouldn't be too much hard work, AEON community could at least suggest it now that they've seen the light with XMR
