Incentives to combine skills such as these are found with all races, so if you have not already created a character it would be helpful to study up on some of the racial skills and see how they correlate to other skill lines. The Khajiit possess a racial passive ability that allows the player to increase their experience gained within the medium armor skill line by 15%.
Players wanting to exploit these abilities should look to the racial section during character creation, specifically the Khajiit. If the player wears more medium armor they will receive a higher boost of stamina regeneration. The stamina regen gained from Wind Walker is based on how much medium armor the player is wearing. Each armor piece the player is outfitted with directly affects the boost gained from a passive ability for instance, the passive ability labeled Wind Walker increases stamina regeneration.
Most abilities within this skill line scale with the amount of medium armor equipped.
