As far as the "mechanical" vignetting of something physically getting in the way of the light (that's what's happening when you put a filter on a very wide angle lens; try a "slim" mounted filter instead), as long as you use an adapter meant for full-frame (the version III metabones for example), you shouldn't have any problems.
As for the "light fall off" vignetting, caused in part by shallow incident angles of light on to the sensor, and creating different levels of fall-off on different sensors based on micro-lenses, among other things. All SLR lenses have relatively long registration distances, which should equate to reasonable incident angles of light onto the sensor (despite some of them being very wide angles like your 16-35). Your adapter moves the lens further away from the sensor, meaning that the lens and sensor sit in the same relative positions as on the SLR bodies those lenses are designed to work with. As far as the "light fall off at the edges" kind of vignetting then, I wouldn't expect any more issues in this respect than would already be present on your DSLR.
The vignetting most people are talking about with these cameras mostly affects lenses with very short registration distances, like M-mount. These lenses were mostly designed to work with film, which accepts light at shallow incident angles much better than a digital sensor, meaning the optical engineers could put the rear lens element much closer to the film plane. This is not a problem with SLR lenses, because engineers had/have to push the lens forwards to avoid the mirror-box. In other words, any SLR lens will face this issue far less than some (particularly wide angle) rangefinder lenses.
