Remote tailcap for Spyder II

[Tachikoma]

I've been using with satisfaction a Wickedlasers Spyder II gx for about a year now and I'd like to install a remote activation tailcap with a pressure pad but WL doesn't make it, is there any company that sells a fitting one?

I've seen a remote tailcap on DX, but I've no idea if it fits your laser.
