The UE cvds have a little hex onto which the actual hex adaptor fits, so no regular hex or hex adaptor will work ( which uses a cross pin to hold the hex onto the cvd ), only option besides voodoo magic is to get a 14 > 17mm hex adaptor which sits on top of the UE 14mm hex, like so:

Axial supply them with some of their rims, but pretty much everywhere else only sells regular style 17mm hexes, or 12 > 17 & 17-23mm adaptors, no 14 > 17mm.
