I think any blacking-up needs to be justified, and the justification needs to be a bit stronger than "because we felt like it" or "because we wanted to dance Border and that's how you do it". The Bacup Coconutters have got a stronger justification, in the form of actual tradition. So no, I don't think they're 'next' to be criticised after Motley - that would be A. N. Other Border Side, closely followed by Yet Another Border Side and Oh No Not Another Border Side.
