There are some chefs who have chosen specific sujis to use as their all-purpose knife instead of a gyuto. Iron chef Hiroyuki Sakai uses a 230 mm Nenox sujihiki, and chefs Hung Huynh and Jesse Schenker use a 240 mm Misono UX10 suji. I don't think all sujis are suitable for this though, and not all users are compatible with this either. Your technique needs to be pretty solid and precise to start with (i.e. when lining up your non-knife hand in the claw, there isn't as much height on the knife), and it probably helps if you don't have super thick hands and fingers.
I ended up getting a 240 mm Misono UX10 suji a few months ago to play with as an all-around knife/occasional gyuto-substitute, and I kind of like it. I had debated getting the Misono since I already had a Shun Elite 240 mm suji (it is a suji profile unlike many of Shun's other slicers, and it's 9.5" instead of 9"), which I did tried using as an all-around knife, and I didn't like it (I love it as a slicing knife though). But the Misono is relatively tall for a suji, and it has more slope as it gets taller at the heel, plus the Misono's very good Western handle gives me great grip, control and comfort for all-around knife work. My fingers are on the slender side, so I even get just enough clearance so my knuckles don't hit the board at all when chopping (prevents me from limiting my chopping position and angle such that my knife hand is away from the board).
