It might work but you really need to do some homework to make sure the top is well connected to the jeep and the gutters are structural so that the rack has something to connect to. Hard to tell by pictures. If the top is designed to handle a roll over, might be good to go. Ask the mfg for their crash test data.
We never trusted jeep tops to have enough structure so we worked with an eco-skeleton rack. If memory serves, the rack weighed 50-60 lbs because it was large diameter, thin walled tubing. Did not flex and was tested to over 2000 pounds static.
Here is a picture of a concept from like 30 years ago. What I find interesting is the design of roof tents have come full circle, back to the box. The rack, tent and even the goofy light bar combined came in at less than Jeeps 165 pound roof limit. Technically, the load wasn't supported by the roof and the rack doubled as a roll bar. The roof could be disconnected and taken out the back without disturbing the rack or tent.
