Need a front carrier with 15kg capacity for a hardtail with no mounting points

Currently been using the Thule Tour Rack which is rated for 10kg, but I need it to carry a little bit more. Any ideas on how to strengthen the rack I have, or other options out there? Ideally budget friendly options. At a certain point it just gets easier buying a rigid fork with lots of mounting points.

Been considering options like a QR Adapter and hose clamps to fit a regular high capacity front rack to it, but I'm skeptical as to how safe that is considering my front wheel attaches to the same thing.

Bike is a Giant Talon 0 roughly 2011 model for what it's worth.
