Listen man, don't attempt this at all. Just starting a thread like this and the questions you have posed so far indicates you don't have enough experience for a project like that.
Especially with the 2017 motor which was made more compact for it's final revision in 06/7.
You could look for same year 600/750 motor, be much more straightforward but would still take some learned skills to rebuild the entire motorcycle correctly.
How beat up is your 600 chassis ? is it worth it ?
Just buy a complete bike with no issues and enjoy life. Learn to work on it and take it apart then later on down the road if you still want to build a Frankenstein you will have a clue.
