I played with the distort map for this a bit, and it shouldn't be too hard.
I placed an always even that made the displacement sprite set its position to the center spoke.
Then on the map I just set up an appropriate number of rows, columns.
You can then set the x,y displacement for each row/ column to the x,y of one of the sprites on the circumference. Of course you would need a ton of spokes, and rows/ columns for it to look good.
Nice thing about this is its a distort map, the sprite can be any size, 1x1 pix even.
