Liquid layout is helpful to maybe 80% of where you want to go, but it doesn't have a complete ability to redesign and redefine your ad layout. Add to it a few possibilities: 1. Text frame options > Auto-Size tab. Here you can give the textframe the magic ability to resize itself 2. Consider using Object Styles on your textframes, where you can pre-define many attributes all at once, including the Auto-Size attributes 3. Pages panel menu button > Create alternate layout. Here you can check on "copy text styles to new style group", ... and *redefine* the size and other attributes of those linked styles. That way, the alternate sized layout can have the styles change the size and leading of the text With these additional think-throughs, maybe you can get the layout to 90%. Most things still require human intelligence and design, of course.
