Changing your race mid game is something everyone does or has tried and if they havent they will at some point.
Just because you CAN do something doesn't mean you
should.
The beauty of the pc version is mods and manipulating the game. We are encouraged to do those things.
Except what you're talking about is using a
debugging and testing command and expecting Bethesda to change it to suit your needs when it's a feature NOT in the vanilla game.
That's exactly what mods are for, so you'll have to wait until the CK comes out.
People use the change race/six option to cure bugs.
So they should fix those bugs instead of working on trying to make this
debugging and testing command behave perfectly in every situation.
Doing this though completely destroys your save file as the character is useless, unless you go cure vampirism assuming its possible as a level 4 vamp.
I know plenty of ways to destroy your save file using console commands, and they're all not bugs. The console is there as a modder's resource, as a way to fix some bugs, to tweak your game for your own amusemant,
with the caveat there can be undesired results.
This exact argument was used with the problems concerning using "Immortal Mode" (tim) and I think most of us stand by that Bethesda has way too much to do already, so many
real bugs to fix, to add something like this to their plate.
