No, I didin't try it, because when I bougth my durga, I had a B4.
Now I drive a TeamC TC02, and because I store a ton of B4 rear wheels, I directly change the rear axle of my TC02 to fit.
You can try this: Put the original wheels, and with a measure tape, check the rear width.
Now, take the hex of your RB5, and put on the durga axes (direct fif, I hope), and mount RB5 wheels, and recheck rear width.
If it's the same, you can use kyosho wheels on the durga.
One more tip: Cut the front part of the rear wing, so this don't mount on the rear shock tower. This will increase the durability og this part
