Sounds pretty reasonable. What is the reason for going 45 minutes over 60? If you're IBUs work out, I don't see a problem. You'll have to use a few more hops that you would at 60, but since it's such a small batch it shouldn't matter. There was a discussion of an all late hop IPA recently where someone argued that anything below 60 will give you a less assertive bitterness, but I figure IBUs are IBUs. If 60 is where you want it, you should be fine. And with a 1.063 OG that gives you about a 1:1 BU:GU, which sounds good for an IPA.
