Is it possible two hibernate.mppaing.xml in a application with same databse?

Team, I have some performance issues because of my existing hbm file. I enabled lazy="false" in most of the place. So, I am getting child objects and it is performance issue. Tell it is possible, Can i configure one hibernate.mapping.xml with duplicate copy of hbml file with lazy="true". If so, what are the thing i need to do and what are the impact i will face?

--->Having two hibernate.cfg.xml on the same project
SessionFactory sessionFactory1 = new Configuration().configure("oracleconfig.cfg.xml"). buildSessionFactory();
Session webSession=sessionFactory2.getCurrentSession();

SessionFactory sessionFactory2 = new Configuration().configure("oracleconfig_duplicate. cfg.xml").buildSessionFactory();
Session webServiceSession=sessionFactory2.getCurrentSessio n();
