Nylon does absorb moisture (it is 'hygroscopic') but I doubt it would be a problem in this application. Nylon 6 can absorb up to around 9%, but nylon 6/6 absorbs much less. Typically, nylon has excellent abrasion resistance (it is used for bearings), better compressive strength & any moisture absorbtion will cause it to swell, tightening any screws used to fix it.

Nylon has a higher softening temperature than HDPE which'll mean it's not as easy to heat-form, and in un-modified grades it suffers more (though not by much) than HDPE from UV degradation.
