Move Native Client for ARM into Chrome on Android (or, wait until PNaCl is ready, and move that into Chrome for Android).
Focus effort on exposing functionality currently available to native Android apps through web APIs in Chrome to make Chrome apps (using NaCl/PNaCl where that kind of performance is needed), rather than Dalvik ones, the preferred mechanism for delivering apps on Android.
At that point, Android and ChromeOS are pretty much the same thing.
