On one side, you say you need millions to do it, on the other side you want a bunch of TMOers to do it by themselves on their free time.
Every big OSS project that succeed was backed by a company (Red Hat, SUN, Trolltech/Nokia/Digia, ...).
If that backing company is not Sailfish, you have to find another one.
Or maybe the missing part is less work than I think and 10 people can do it in their free time?
And about the consistency : it is hugely needed as it is directly correlated to usability.
