Over Canopy Rack

I have a 2020 Tundra CrewMax with a Leer 100r canopy (I believe that is the model of canopy) which I've owned for about 7 months now (canopy came with truck). I am looking for a rack to hold a boat/kayak/various longer objects that will go over the canopy like the one in the photo below but still sit on the bed rails of the truck.

Wondering what my options are other than to get a custom fabricated rack?

Yes, the canopy I have now does have the Thule crossbars on it, but I don't think they're rated to hold the weight of an aluminum style fishing boat nor are they spread apart sufficiently to carry longer boat/kayak safely(yes, I understand I could buy an extra set of crossbars and put them on the cab of the vehicle to spread out the weight of the items on top - but I'm not that interested in that option even though I'm sure it'd be cheaper). The canopy is the style that is contoured to the shape of the cab/bed rails and goes over the edge of the bed sides if I'm describing that correctly. After a bit of research I've discovered there are lots of options for domestic trucks (I understand why) that fit my needs perfectly, and dozens of the 'overland' style racks that would work for me without a canopy. Maybe I need to go with an 'adventure style platform' rack?

Just wondering if anyone knows of a rack for the 2.5 gen Tundra like this one below (and yes, unfortunately I'm in Canada, so there's that aspect......
