Ignoring the fact there's exactly a 0.00% chance of that happening, what other major EU airline partner do you see coming to the rescue? LH is not leaving *A, LX is owned by LH so same applies. Just what other major EU airline is there? The only other "major" airline that I can think of would be AF and frankly given their propensity for strikes I wouldn't want that and being a major player in ST I doubt they are open for a change...
