Yes (assuming your Sugino triple is 110/74 BCD, which the XD2 from Riv is) -- you can change out the middle ring for a 40 and replace the outer (big) chainring with a guard.
If you're just trying it out, change the middle with the 40. After riding/testing, if the gearing is suitable for you, then swap out the outer for the guard. >From my experience, if your front derailer is working fine, I'd leave it alone. (I've managed to mess up "perfectly adequate" in attempting to fix it better too often to count. YMMV.)
