I say let the interested parties put up the Buddhas, stars of David, and whatnot on the site. Once it gets made private land, all that stuff can be taken away and the cross left.
Two VCs were won by the 3rd in this war. Rifleman Kulbir Thapa, the first Gurkha to be so honoured, won his during the battle of Loos on 25th Sept 1915. Having been wounded, he lay for a day and a night with a badly wounded British soldier behind the first line of German trenches. The British soldier kept urging him to save himself but he refused. At dawn, the mist gave him enough cover to bring the soldier to a safer place, then he went back to help two of his fellow Gurkhas, bringing them to safety one by one. He returned to the British soldier and carried him in broad daylight to the Allied trenches under enemy fire. --The 4th Gurkha Rifles.
I would welcome other memorials perhaps in other places, possibly in a geometric space of several hundred meters. But this cross is beautiful by itself. I would not want to change that.
