Which twistie are you refering to? As far as I know, the L2P is a clickie also (at least mine is). I'm not 100% sure, but I don't think the tail will fit the L2D body, different threads. If you wanted to, you could use your L2D as a twisty, just click it on and then twist it off/on. Dont know how the the different levels would be affected though. Might work fine as long as you're under the 2seconds limit.
