Yeah, Shimano makes banded direct-mount adapters, but you'd still have to buy a new 6800 or 8000 direct mount front derailleur. And even if it does reach, if the chainline is wrong, it will never be right. Fix the chainline first.
Case in point. Years ago I did some work on a Cervelo with FSA cranks with a 24mm spindle. The owner had replaced the threaded outboard BB bearings with Shimano, a deceptively smart move because Shimano are less expensive and more durable. But the Shimano bearings were about 1-2 mm wider than FSA. While the spindle was long enough to clamp the left crank properly, the drivetrain was never happy cross-chaining from the big ring. Big-big was impossible, and shifting to the big ring from cogs 2-3 in back was hit-or-miss.
