You can take the front hood off completely if you want and lay it face down on the ground using a soft blanket to protect the paint finish. Then use weights to hold the bracket in place while the epoxy cures.
Before you disassemble anything, be sure to mark the connections so you can re-assemble it back the same way.
I agree with this, take the front off and lay it down. Even if you add a thickener/binder to the epoxy it will want to flow and if you try to this while the cap is vertical it will run.
I've used West epoxy, you can get a faster hardener if you want. If you are concerned about appearance you can even get black pigment to help it blend into the original.
On the main contact points, after reattaching it to the cap, you could also lay fiberglass cloth across and epoxy it also.
Also, from your picture, it almost looks like there is wood embedded into the fiberglass. Mine has this and there are screws that are used to attach the frame to cap. I worked a insulated truck manufacturing company that did this, we placed them in key positions depending on where the piece went. Same thing in boat manufacturing. You might check to make sure you don't have the ability to use lag type screws to help attach the cap to the frame.
