I think the best option for King George V and the Romanovs would have been to reveal that Alexi suffered from Hemophilia. In that case sanctuary in Great Britain becomes a humanitarian issue. I don’t think the British public would want to turn away a sick boy.
The next option would be for the British Government to make it clear that the Romanovs would be staying in England temporarily until the war is over. Once the war is over arrangements can be made to move the Romanovs to a neutral kingdom like Denmark or Norway.
