How to manually update android browser with latest (nightly) webkit?

Question

Is it possible to update WebKit behind the Android 1.5/1.6/etc (prior to 2.2) browser?
I know latest nightly WebKit builds has great HTML5 support.
So, my intention is to provide html5 video streaming (and other features) support on all those droids.
Previously I was able to update WebKit engine on different devices with older Safari to meet my requirements (on any mac os x distros it's easy as updating WebKit.framework).

Thanx.

Not without rebuilding the firmware, and even then, you will probably have extensive work to do.
