@staticV3 said I am not sure exactly how to interpret this, but my guess is the +3 treble trim on the LS60 will get you in the zone. This doesn't seem to have an outright rising response or anything.
e: Based on the second graph, this looks like it has the typical B&W off-axis treble splash, so if you were going to EQ the LS60 to sound more like this, you'd maybe want to boost a little around 3-6khz and then give it a little nudge between 7-15khz.
It's sort of apples and oranges, because the LS60 tries to have smooth dispersion, i.e. about the same frequency response in all directions with a steady decrease in treble. B&W tends to shoot some extra treble off to the sides and have less treble out front, which is a bit of a 'special effect' and can be hit-or-miss in-room. The difficulty is you can't replicate this kind of directional effect with EQ (or any other DSP tool really).
If you really want the uneven B&W splashy thing, I think your best option is to buy B&W... but I wouldn't really recommend it. This is a version of what people mean when they say "showroom sound". It's not necessarily a bad thing and I have owned (and still own) some B&W speakers. But I would say the KEFs easily beat them in terms of clarity and realism.
