Their effects were very vague though. The cards just kind of did certain things at the time that was about it. Actually giving them a proper effect would be interesting but would probably make them unplayable and so printing them would be a waste of time. We don't want more Ra's do we?Well, you never know. I mean, people figured that they'd never print Slifer with its anime effects, yet they did. If the Legendary Dragons got printed, they'd probably have their effects nerfed somewhat anyways. And there have been monsters that doubled as spell/trap cards before- the Crystal Beasts. And there are also a few trap cards that double as monsters (Metal Reflect Slime, Zoma the Spirit, and Tiki Curse to name a few).
