Oh wait, that didn't happen, instead we got a giant multilateral agreement in the form of the TPP.
I don't think that the ability to switfly get FTAs with the US is simply a matter of relative size wrt population and GDP. There has to be sufficient interest from both parties and a willingness to make concessions. The willingness to make concessions is likely to be greater for the smaller party (in this case the UK), and I believe, historically, the larger party (eg. the US or China) has tended to use that to its advantage.
