No there are no technical limitations to having mixed system-wide eclipse updated through apt and local plugins installed through Eclipse's Update Manager.
I have done lots of test with the packages in my PPA and in all cases things just work perfectly. The approach I took was to use Eclipse 3.4's dropins folder to install eclipse plugins system-wide in .debs.
