What aspect makes you must unsure?
The whole cloning idea is creepy to me. I really used to think Clone Wars was a title, the name of a place or something. I've begrudgingly accepted that "clone" means clone even for my own stories, but that's where I come from generally.
To me cloned Jedi seem to raise the creepy factor. The depiction of insanity could be difficult without making things just too dark. I'm trying to imagine a cloned (perhaps insane) Luke in the OT, how that would fit with the tone.
Is your concern more story-based about staying away from dark force users? I'd say if that's a direction you don't want to go, probably best not to go there, especially half-heartedly.
