Does it "work"? "Work" is a matter of directorial vision. If you're the director, the best thing you can do is test, test, test. If you like the results, nobody can tell you it doesn't "work". Do your homework, plenty of preparation, and consult the necessary production and post-production personnel first. Recruit a knowledgeable FX artist and let him/her in on the tests.
