Yes.

I'm getting help from Pascal Rapicault, p2 guru and he advised me to do 
2 things :
- use p2.inf to basically prevent that m2e-wtp and m2eclipse-wtp are 
both installed at the same time, using the fact they're singletons. 
(http://git.eclipse.org/c/m2e-wtp/org.eclipse.m2e.wtp.git/commit/?id=d2cce866b6ee1bb8e3d5cff8c61bce288d265537). 
That part works.
- hack content.xml in content.jar from the gen'ed update site to try to 
make m2e-wtp updateable from both m2eclipse-wtp and m2e-wtp. Since tycho 
and p2 don't allow that part during build time, I wrote a groovy script 
that does that during packaging : 
http://git.eclipse.org/c/m2e-wtp/org.eclipse.m2e.wtp.git/commit/?id=621585b55a31f1d8efcdee643ed7ae1bd0b406f4. 
Unfortunetaly, even though the script behaves properly, the effect on 
plugin update doesn't work as advertised. Pascal is looking into it.
