WordPress and WordPress MU are complete PHP4 hackjobs. It is a developer's nightmare to fine-tune any website that uses these platforms. Since BuddyPress just turned stable and barely has any plugins, it is not worth its salt as a Social Platform, unlike Vanilla 2, which uses the MVC design pattern and ships with just as much if not more out-of-the-box features. The OP's suggestion makes 0 sense.
The main reason, I find, that people use WP is because it is free and does the relatively simple task to managing and displaying a blog decently out of the box.
If WordPress was completely rewritten (like Vanilla 2 was in lieu of Vanilla 1), then I'd change my argument. But you'd lose the thousands of plugins it currently supports, though perhaps only 100 of out them are actually production-ready.
