Been able to bend any required aspect of Frisco to my will and it's been fabulous. The one, last thing to nail before launch is this: How can I get the "One Column, No Sidebar" template to work on just my single Group pages?
Selected the "One Column, No Sidebar" but it still displays the sidebar no matter what I do. What's curious is that I've copied that "One Column, No Sidebar" page template from the BP Default theme in to Frisco's child theme directory, renamed it to "Groups One Column, No Sidebar", gone back in to the "Groups" page and it appears in the template popup. But when it's selected and the page is saved, it reverts back to the default "One Column, No Sidebar" from the BP Defaults directory.
