Which is how I've played Hitman games since the beginning!
It's the whole "I'm a bald ninja" thing that I never was good at. I'm at my best if you ask me to figure out how to "fool all the security in plain sight Mission Impossible style".
For example, to do Sniper Assassin on Bangkok is really easy once you figure out that you can smuggle the sniper rifle upstairs into the Queen Suite Kitchen via pipe climb out of your starting hotel room, and then clear the entire Queen Suite bloodlessly when you accompany Ken Morgan to the Queen Suite as Hotel Staff (everybody just goes upstairs and stays there if Ken Morgan cannot complete the tour).
You can then KO Ken Morgan before he can complete the tour... take all year if you want to take the sniper shot out of the window to kill Jordan Cross (I think that's also a challenge), then casually walk to where you KO-ed Ken Morgan. Shoot him pointblank with the Sniper rifle and just waltz on out of the place as Hotel Staff.
That's the stuff that comes naturally to me.
P.S.: Oh I forgot to add that in that Pro Save I also had the Pointman disguise.
