That's fine. the road FD doesn't care what crank is used as long as the chainline is such that it can reach the chainrings and handle the tooth differences being run, within it's limits. A road triple FD DOES care what shifters are controlling it.
Even then a person could come up with a way to move the FD out further with a spacer or something like this.
