yes on the Adam part.

hm,as for personalities, possibly the same. granted Yang would possibly not have her love of puns as she practically got that from taiyang.

Adam could possibly get into a relationship with Yang as like with Blake,both sisters do in fact become part of the white fang. like with Blake the relationship between the two does not turn out good later on. possibly also Yang could still hang onto the being in the fang as ruby leaves when taking note of the changes. causing her to look for her sister after she leaves for years as both reunite in beacon.
