LOL - All my DA revolvers are DAO, simply because I never shoot them any other way. I don't see the need of altering the sear engagement but bobbing the hammer spur is a good idea if you're going to carry it concealed. YMMV!

PS: After posting the above I realized I lied to you all. My carry gun (386 Night Guard) has an APEX DAO hammer. I tend to forget about it because I never tried to cock the bobbed hammer to remind me it is DAO.
