Holy shit! You mean Kabuto used Edo tensei to revive Karura... This competely dwarves the bitching about Kiba getting the second harem IMO. I'm pretty neutral about it, not especially enjoying it nor hating it, I'm just waiting to see how you'll develop it.
Still, I do wonder what will happen with Karura... While I'd like her to remain alive (either joining the harem or not (poor Gaara of she does, first his sister then his mom)), you could choose to have her find some closure and pass away; a 'failure' to save someone might help Naruto grow (I'm saying failure because Naruto would probably prefer to reunite Karura with her family)
Also on the Anko front, you're hinting at a possible solution by having one of Naruto's lovers willingly explore the BDSM aspects of sex with her; or maybe have Yuffie fill this role.
