I haven't seen anybody that makes one for viridian. But all three of these companies do custom work so you could probably get something worked out. If you are using a gun with a more common light like a surefire X300/X400 or streamlight TLR1/2, then all three of those companies can set you up pretty easily. I have a raven for my Sig 226/X300 combo and have been very happy with it. The wait time for raven is up to around 4 months right now, which is my only personal gripe.
