No, this is way too complicated.
The Betrayal by @JosephMartin, SA/SnA (1:55)
Silent Assassin + Sniper Assassin
Las Ville Des Lumières by @o_O, SA/SO/DE/FW/!KO & Speed (1:24)
Silent Assassin + Suit Only + Default Equipment + Fiber Wire Only + No Knockouts
Not good enough to beat your par but I think it's a pretty smooth route. Shame I couldn't stash all the bodies on the fiber wire route without it taking forever. Might've needed to take that bodyguard all the way into the basement, though I probably could've gotten away with it.
Here's a couple interesting random contracts I found. They seem like they've got some depth for more exploration.
Who's Next is Silly by Mooldenau (1-10-5269815-78), SA/SO/DE/FW/NE/!KO + Speed (3:20)
Silent Assassin + Suit Only + Default Equipment + Fiber Wire Only + No Evidence (All Bodies Hidden) + No Knockouts
I got my own time down another 25 seconds or so but I'm sure it can get even faster. It seems like a very interesting contract, deeper and less random than the target selection initially suggests.
Heavy Rain by Skyplayer (1-07-3752327-61), SA/SO/AO
Silent Assassin + Suit Only + Accidents Only
This is actually a lot harder to do fast than the simple premise and target selection suggests. Turns out bodies falling into the market causes some trouble.
