You could try a diaper cover type thing such as regular underware over the diaper. It keeps the tabs from being able to be pulled. My 11 month old son likes to be naked too. He also likes the new big boy underware...like his 7 yr old brother. He is so proud to be like everyone else it seems to keep the diaper on. My 2 yr old daughter is in pull ups (although more expensive) wich helps her. And I've been trying to potty train both my youngest. If the diapers are such an issue for them they need to use the potty. I don't expect that either of them really use it yet, but sometimes they both actually do it. :)!
