If WW did pull the MAN-NOC for whatever reason, I'd guess that Jet2 would be the more likely ones to do this.
Remember that they have a relative lack of short sector flying ex-MAN (lack of domestics or ROI routes) so one would assume that they'd jump at the chance of doing this if the opportunity arose.
I am sure this fact is also not lost on the management both of MAN and NOC airports...
