How quickly achievable it is would depend on the requirements that the WG 
agrees upon.  If we assume minimal requirements (such as "we need to protect 
only IPsec traffic from a QC" and "a static shared secret (PPK) is 
sufficient"), then it's straightforward (the current draft is overkill for 
those requirements; IIRC, Tero outlined one such solution a while back).  If we 
insist on maximal requirements (such as "we need complete anonymity, even if 
the attacker has a QC", and "we need a complete PPK management solution"), 
well, Feb 2017 would be a bit on the optimistic side.

I would certainly hope so; the current work assumes that there is some 
out-of-band quantum resistant mechanism for distributing (possibly static) 
secrets to the IKE endpoints; that's an acceptable solution in some situations, 
but not in others.  Eventually, we'll need a replacement that'll work 
everywhere; it's just that currently the crypto technology isn’t there quite 
yet (as McEliece has impractically large public keys, NTRU isn't universally 
trusted, and everything else is too new to bet the farm on...)
