Not easily. 5 line bar with 4 line kite.
According to : http://www.kitesurfguernsey.com/reviews/north-trust-quad-kitesurfing-bar-2013/
the Ride flies well with a 4 line North bar so I'm guessing that the high Y split doesn't affect the flying characteristics of the Ride.
To make the 5 line bar work you would need to make a line extension to attach from the 5th line to the pump loop on the leading edge. You want this to have some play in it but not be floppy - similar to the way that the optional 5th line works on the North 4 line kites (Evo etc).
Let us know how the kite flies if you do decide to test it out.
