Adaptive damage should be used

I think more champions should share the design of in that he can go either AD or AP and be effective with either, each having their pros and cons. Giving some champion abilities AD and AP ratios along with adaptive damage would probably make them viable in other lanes. W for example could have an AP ratio and deal magic damage if your AP is higher than you AD effectively allowing her to have more versatility and making and AP build on her actually be viable. Overall adding adaptive damage would probably make more champions have interesting build paths based on what kind of damage they want to do.
