Ideally m2e-wtp would disable m2eclipse-wtp when installed, but I'm afraid it seems impossible (yeah I suck at eclipse/OSGi stuff). 
So that means the only way to install m2e-wtp for existing m2eclipse-wtp users will be to either start from a pristine eclipse installation or uninstall m2eclipse-wtp beforehand, breaking the update process for products already embedding m2eclipse-wtp.

Using p2.inf on a repository, we can add extra actions to installations. Maybe there is the necessary stuff to uninstall an IU if present... I honestly don't know a lot about those p2.inf files: http://wiki.eclipse.org/Equinox/p2/Customizing_Metadata#Touchpoint_Instruction_Advice:
