CWL to EDI and JER could be W Patterned from EMA or another base with some slight rejigging gives 2 a/c as now.
Although there are a few routes that might tempt them to put the 3rd a/c back if LH allow them to source extras BCN was always good, could return the EDI to 2 a day always did ok, IBZ was only dropped because of pax problems but would make money.
The problem Baby have with CWL is that you need profitable 1-1.30 hr sectors (domestics / near europe) to make the aircraft and crews pay their way that's why the 3rd aircraft was lost 4 sectors a day (sometimes only 2) can't cover its cost let alone make money. You need at least 8 profitable sectors most days for that third aircraft. Because crews can't do double meds (can in Ryanair !) it means you need an extra crew per aircraft per day if you are not finding a profitable extra two sectors per crew shift. Baby tried AMS, BFS, GLA, GVA and couldn't make them pay their way on the 73. That makes the operation more charter than LCC and that is the fundamental problem baby have across the network at the momnent.
No one really knows what will happen with LH and it is not November (big announcement month) yet. Hold your breath and keep everything crossed because Fly Be won't replace what you lose at CWL if baby go. Just be happy they are there at all for the moment. Better times will come and having Baby at CWL isn't keeping anyone else out. So cut them some slack and support what they are doing !
