After I completely back up my Pre, is the following possible?

If I download this version of the webOS Doctor

//palm.cdnetworks.net/staging/rom/webosdoctorp100ewwsprint.jar

can I run it from my local machine?

If yes then can I simply remove the unwanted IPKs in ...\webosdoctorp100ewwsprint\resources\sprint.tar, then run the webOS Doctor and the Pre will be reloaded without them?

Thanks in advance for any input.
