This will not happen, and it is a poor avenue for "disruption".
There are plenty of good lawyers from middle tier firms, solo outfits, and boutique (i.e., specialty) firms. These practitioners already service the vast majority of people needing legal assistance (including small-to-medium businesses).
Corporations choose BigLaw not because they're the best (boutiques and specialized mid-tier firms generally produce higher-quality results in any given area of law), but because BigLaw firms have the resources and capabilities to handle anything that a large corporation can throw at them. When you're dealing with dozens or hundreds of litigation cases across the country in a dozen or more areas of the law, you go with a BigLaw firm b/c that one firm can handle all of your legal matters, reducing complexity and cost.
