I agree with most of what you say aeulad, the problem is that TCX will surely not want the risk on their shoulders.
It is understandable that TOM want to fill their aircraft from DSA and EMA and so seat sharing is not an option.... The winter TCX fights were pulled due to costs of outstationing aircraft and crews, this is made worse by a lack of other major operator support.
Ive said it time and time again, i believe that as things stand Jet2 would be the only saving grace. Whether the airline or the management want that to happen is another matter entirely however.
