WebLogic is already built on top of OSGI, like all major JEE servers:
http://www.theregister.co.uk/2009/10/13/oracle_weblogic_roadmap/

I think that in the Weblogic/Websphere world, the actual JEE parts
(EJB and servlets and such) are actually the smallest part of the
stack.  You got messaging products with a gazillion adapters into
software products, rule engines, BMP engines, ESB, BI and many more
enterprisy thingies, which is probably why Oracle felt that Weblogic
is sufficiently different from Glassfish so they can continue to
charge $25k/processor for Weblogic Enterprise Edition (2008; this was
the first Oracle price and a 47% increase compared against the last
BEA price sheet before the takeover by Oracle) and give away Glassfish
clustering away for free.
