I had looked at water-jetting a center plate, with the 5 ton beadlock patterna and the 2.5 stud pattern, sandwich that between the 2 halves and bolt down, cut off the 5 ton pattern and you have some 2.5 ton rims, I had planned on 1/2 plate, widens the rim to 10.5" but no welding or chance of warpage..I'd try this with the older rims that had a bunch of bolts, not the newer ones that have 1/2 what the others did...somewhere spicer has pictures of the rims I was looking at...
