I think this would involve removing the Crown guard? I know.... might only involve removing guard once or twice but then accidents only need to happen once or twice, for a serious injury to happen. So I wouldn't remove the guard.
The planer, I think I might have a go at that, not that slow, what 1mm, 2mm each pass, lighter on the final cut, clean up planer ripple with a hand plane?
Not always, but it is permissible as long as you form an effective guard and work holding device by other means such as shaw guard or a tunnel that prevents your hands getting near or the wood taking flight. I have a sliding table and my saw tilts to the right so I can clamp the cill to the slider and push the slider so that my hands are no where near the cill. I stand to the left. All I then need is a guard to cover over the exposed saw blade, which I can attach to my standard fence. At the moment it is the best and safest technique I have worked out. Obviously as soon as you have finished you put the crown guard back.
On the planer you may be able to start with larger cuts and then as the width of the slope increases reduce the depth of cut. So my first cut might be 3mm and the last less than 1mm. The problem on the planer is supporting the cill to ensure you feed at the correct angle and it is difficult to keep the blade guard properly set. A jig in the Thicknesser is probably the safest. The downside is you cannot make rebated cills this way
