In what way?
Few people, I’m afraid, are allowed to modify Comic Sans, and even fewer, will. There are even those who think you cannot modify Comic sans to look very nice. ;-)

Part of me feels it’s heretical to modify such a specimen of typographic wonder.

It’s almost like...like re-designing the Pope’s big funny phallic hat. You probably just shouldn’t?

Just buy a nice font from Blambot or Comicraft.

And burn the Pope’s big funny phallic hat, while you’re at it.

Maybe you’re thinking of Apple Casual?

In any case, do yourself a huge favor and follow James Puckett’s advice.

Could be HVD Comic Serif.
