That wouldn't work - the large disk would still be locked after the swap, so you couldn't write to it.
If you're lucky the gamesaves will still be on the hard drive. It would be sensible, but not essential, to use a recent live enabled game (Halo 2 or later) to update / restore the stock dash before you start.
If the gamesaves aren't there then you could get a USB adapter (like
this one) and use a standard USB stick with Xplorer360 beta 6 to put a Krayzie 1.1.1 gamesave on the Xbox, and start from scratch.
The final alternative is that you could hotswap, but as you've overwritten xboxdash.xbe you'll need to find a copy of the one you got rid of, and that's not easy because in a softmod Xbox xboxdash.xbe is not the standard Xboxdash.xbe - it's an old live dash renamed! Rather than messing about, it might be easier to build a new softmod file set using Kingroach NDURE 3.1, and replace the existing C files with the Kingroach ones, and also copy the Kingroach E files to your E. You can use xboxhdm or Xplorer360 to copy the files after the hotswap - either will work.
Among the advantages of upgrading to Krayzie and Kingroach is that they use a shadow C to hide the real C, so you can't accidentally delete xboxdash.xbe! (IMG:
