Is it called 'Swing Over' now? It has happened to me a few times in the USA, at LAX, e.g. 24L and 24R and there it is/was called 'Side Step'.
At LHR I was finals 27L in VMC and and asked if I could still make 27R, answer 'Yes', 'Roger, you are now cleared to land 27R' in that case I would, having visually established finals 27R, done the missed approach for 27R.
