Don't try to convince system-scale project leaders of enterprise-scale architectural decisions or you will "die". Especially if you don't have good examples at hand. (Should project leaders be "convinced" of architectural decisions at all? Or should there be a "trust" relationship with the employed architects?

You can obtain decoupling (independency), reliability and performance at the (low) cost of redundant data persistency. When you stick to "calling services" you gain benefits at the level of application construction, but at the cost of higher loads, less predictable performance, scalability issues and higher costs in business level reorganizations.
