I don't think it's too hard, the way Issei treats the girls isn't that different than Kiba being a gentleman. It's probably the one trait Ishibumi felt he should keep so Issei making girls fall for him had a good basis.

Like Koneko and Gasper said (in the dub atleast) "Your a pervert, but your sweet" and "Yeah... but your a nice perv", so maybe Issei with all Kiba's traits? ...Yeah, a bit hard, but some of them? I can see that working.
