Can't get outback hull up. Okay to car top hull down?

Hi all,

New outback owner here, loved my first few trips out. I'm wondering if it's okay to car top hull down, on curved cross bars. I can easily get my kayak on my subaru hull down and am using cushion pads on previously purchased curved cross bars. However I can't figure out a way to get my yak on the bars hull up without risking dropping the kayak, or scratching up the H-bars in the stern.

Is there an easy method to get my yak up top, hull up? Otherwise will I be okay assuming most trips are 1 hour or less? The first few trips show no flat spots but figured I'd ask. I probably at least would be better off with perfectly flat Thule bars but I'd of course prefer not to spend more on bars. Thanks!
