K3 fairing on K7?
 

I am planning to buy an SV after reading so much positive stuff about the bikes and I found a few good offers...
One of them looks especially tasty but the bike is K7 with an awkward looking screen.
I assume taking it off won't be a problem, but is it possible to buy an entire SK3 fairing and attach it? Is this some sort of a major job? is the part expensive?
