(OBSOLETE, READ NEW POST) CSS solution: /* remove layout selection in create page dialog - 4/15/11 */
 * 1) CreatePageDialogChoose {display:none;}
 * 2) CreatePageDialogChoices {display:none;}

Maybe I will find way to make the standard layout blank, but my current code doesn't work because CreatePage.options.format.submitUrl overrides on opening of the dialog, and for me setting onload for the dialog doesn't work.
