heh, right now researching the exact opposite. Bikini top instead of Freedom Top panels.
Leave hard top on, remove panels, install MESH bikini top (keep crap out, reduce sun, even drizzle/light rain, while circulating air etc.). From the pics of panels removed (haven't even had a chance to remove mine), cannot see if you can fit the straps between the roof and the bar. Looks like there is some clearance? Otherwise anyone ever done this, if so how so?
