First and foremost- SO happy to hear that you will be ok. Getting hit is a nightmare shared by each of us, maybe even *the* nightmare. Take care, and rest-up. The road will be waiting for you when you're ready, and maybe this will give you the urge to come back even stronger than before.
If you're really looking at a no-holds-barred, once in a lifetime opportunity to get anything for your next bike, I say forget the factory commodity bikes and go with a full custom build for you, envisioned by you, and truly unique. You can use your recovery time to plan every facet of the build, research parts and materials, and speak to builders. You don't need to have an unconventional body shape to go custom. Geometry that suits your riding style, tube gauge, custom rake forks, and build kit can be planned as a whole and integrated to work as a system that pleases you best. While you can buy a frame off the shelf and create a showcase for premium parts, anything planned and executed in a single-source process can offer more enjoyment in the long run.
Personally, I cannot offer a high enough recommendation of Bill Holland and his crew in San Diego. I bought a bike from Holland, and it exceeded my already high expectations. Plus, you'll actually get a bike quickly from this small custom concern. They don't accept the geologic-scale delivery timeframes of some hand builders, which was a major bonus.
Bill's craftsmanship is second-to-none, and the shop is one of the few custom concerns that genuinely applies the same attention to the fit, component selection, interview, paint planning, and final assembly as they do to the business of welding the frame. Plus, all 4-5 of the people who work there and work with customers are sterling people and memorable personalities. You'll get what you want at that place, and you'll want to stay in touch with them. It's a great experience that yields a great bike. Buying a factory machine can be fun, but it's more like a shopping trip than the custom route.
There are a lot of great builders out there, and the best thing you can do is find the shop and the builder that speak to your interests, philosophy, and riding style.
Regardless, tell us what you decide, and do post photos when the build is done.
