It's not. People have suggested it before, and it's always been a terrible idea.
Ulfhir 说:
Lorewise it checks out because the Night's Watch do send recruiting parties all over the place who gather mostly prisoners.
Other than Daeron and Yoren, we don't know of any Night's Watch recruiters. So it does not check out, lorewise. It's a common mistake most people who deal with ASOIAF makes, one instance does not make tradition. It's like GoT for CKII, just because Daenerys can hatch a dragon does not mean there's a chance anyone can do it and that she just got lucky.
Ulfhir 说:
Gameplay-wise, it would give the player a way to recruit them (rescuing from bandits etc)
Here we go, you don't care at all about lore, you just want the Night's Watch in your party. That doesn't really make sense though, lorewise, does it? If they joined you, they'd be deserters and harboring them is illegal in the lands of Westeros, the punishment being death, if I remember correctly.

Lastly it adds cool flavour to the game without all the effort of scripting a working Wall/Whitewalker mechanic.
It adds no flavor at all, they're still just manhunters.
