If any two (or more) gigs are actually offering the same thing as each other, that is against TOS.
If you know that one or more of those Gigs are poorly written, why not simply improve that rather than making many gigs that are the same with compete with yourself and make you look odd for anyone who looks and sees that you offer the same thing over and over - which looks dodgy.
Forget your Fiverr ID, think of your own reputation. This is not a game, this is life, if people think you look like you are playing games more than doing Great Work, they are gone. (or they are working out how to play a game on you)
