There are some add/drop DWDM muxes that can plug into your CWDM stuff
( I know not yet purchased )
When I looked at the 9Ks I thought ( just double checked ) that the
10G was provided by SFP+ not XFP

The 9K supported GBICs are here -

I'll send you a proposal a vendor gave us for doing exactly what you
want ( we already have 1Gb CWDM for SAN, DMZ vlans and some other
funky traffic we did not want to run over our "normal" 10Gb links.
