I would suggest to self publish your plugin in the new repository:

http://plugins.qgis.org/

You need an osgeo account to log in there.  Once logged in, you can
upload you plugin and it will be made available via the plugin
installer in 1.8/trunk. Incorporating the plugin into QGIS core to
replace the existing tool would probably be difficult since numpy is
not as far as I know a dependency of QGIS.

Note the new repo does not have a very wide circulation yet, but this
will change when it becomes a default repo in QGIS 1.8.

Best regards

Tim
