I see no problem with that. There is the well known "Hobbit-strength" and I also believe even in the case of the Nazgul "wraithifying" did not happen in several weeks or months but in years. The Rings granted a mortal longer life, and I would say the "fading" occured only when the mortal exceeded his normal lifespan too much. The Nazgul appeared several hundred years after the mortal Men got their Rings. Bilbo was more or less okay. Gollum did not wear the Ring much in the latter days. Frodo was okay with the Ring itself, but there was the presence of Nazgul, the much stronger "awakened" will of Mordor, the will of Sauron focused contretely at him, and mainly, in the end, the Morgul-wound. The fact that Frodo almost faded at Bruinen (as Gandalf put it) was not an effect of the Ring, but mainly of the Morgul-wound.
