clutch change.

[Ianr]

I would say - use tippex or touch up paint to mark the location of the clutch you remove (you can then put it back if you want to later) and go ahead with any changes you want to do, if its no better you can at least go back to how it was.
Can't see any issues over balance - standard engines were not balanced - yours is - whatever you do it can't be worse than standard
