That idea is suggested in my article, in the paragraph where I suggest forking Chromium to add a new tab type.
Effectively you'd have web and newweb tabs side by side. You'd get some of the Chromium infrastructure 'for free', like user switching, the nice tab dragging code and so on. NewWeb tabs would not contain the URL bar, back button, reload button, bookmark star, extension buttons etc. But it might reduce some of the mental overhead of having to switch between 'browser' apps.
