Another option is to really ramp up the power-gaming level and switch them to Oathbound. Let them play whatever they like provided they use the Savage Species rules.
And then kill them. No, not in one session. Let them be really powerful but in a place where everyone else is really powerful and possibly more powerful. Don't treat it as a one-shot; sketch out a campaign arc (preferably with horror themes) that will take them through a few sessions... and then engineer a TPK consistent with the world and the storyline.
I'm doing something like that right now. You want a computer game, you can have one....
After that, see if you can persuade them to start in Midnight as my esteemed colleage, Ash, mentioned above. Ther next step would be to start them in your homebrew world on your terms.
As an added bonus, you will probably have a new enthusiasm for your own world by this stage.
