I would imagine it could start by eliminating bionic, which seeems designed primarily to keep hardware OEMs happy that everything is under a weak (BSD style) license.
ChromiumOS uses a standard Linux libc (probably glibc) and is more compatible with commonly available userland software and the newest ARM hardware and ABIs.
The Chromium build system is also more suited to building an OS than a Java application.
I'll assume that Dalvik stays, and that the Android API is supported.
The Android window manager is pretty powerful (actually underutilized on phone form factors, as it supports movable frames and overlap, though that is not apparent from using it. Chrome has it's own window manager, as well as it's own desktop UI.
One question might be what direction Google TV goes in, possible with a more exclusive partner arangement. Does it make sense to build Google TV apps on Android, or should it move to more of a web model using Chrome? (This isn't neccessarily assuming that Google TV survives as it's own product line).
I haven't seen what information has been publically released about Google Glass development, but it's UI could be accomplished equally with Android or Chrome underneath, and eventually it makes sense for them to be webapps.
Another possibility, seemingly out there, would be for Android to move towards a WebOS/FirefoxOS model where core applications are built using HTML and interfacing with exposed libraries, but Android apps would still be first class citizens.
