I have tried this with an older and much weaker version of Suzie. It played 
positionally better than the Alpha-Beta version, but the rate of very 
strange moves also increased. UCT greates a more unbalanced tree than 
Alpha-Beta and the programm has therefore even more chances to "cheat". For 
the same reason extensions do not work so far in Suzie.

But I tried not with 0-1 but used the full eval. Maybe I should give it a 
second try. But as I work now 45 hours/week on Computer-Tomography (which is 
also quite interesting) and comute each weekend between Germany and Austria 
its difficult to do.
