Keep in mind that with dex 15, you could qualify for twf without ranger.
A race with int +2 can get you 2nd Lv bonus spells, you could multi class with such a caster and a more martial class.
While an 11 or 13 wisdom doesn't get you enough bonus spells for my taste, I usually just don't bother with saving throw spells. You could also stat bump at level 4 or 8 to get those bonus spells I think are critical. Though waiting that long, even with a multiclass could feel pretty lacking. Especially since you likely want to put that Lv4 stat into Str, maybe even Dex. But you could do something like a 4Ftr(specialization and 2 other bonus feats) or another full bab class and take something like Magus or War priest 4 and then you would not even have had access to those 2nd level spells until 8th level. I don't think i would be satisfied, I would rather take a 1 level of full BAB, at least levels 2-5 as a caster then consider going back to martial classes so I had those spells earlier.
