This free mod from BCSE will get you close... you will probably want to edit your products.tpl (or make an alternate products.tpl for these items) and if/else this... in products.tpl, lose the thumbnails, and set it up as a table format... not hard to do. But the BCSE mod will be the guts behind the page to let your customers use one button to add everything to the cart at once.
Please report back if this works for you.
