You don't need to stay with Suzuki for a front end swap. I have a YZF600R front end on my 86 VFR750.
Your biggest challenge with be fork length, as they should be close to the original length. It looks like the Intruder has very long forks, and I don't think ANY sport bike fork's would be long enough.
Also need to think about finding a stem that fits your frame, steering stops, ignition lock, to name a few...
I think this will be very difficult. Hit google and see if it has been done.
