The 4 rivets holding the striker plate will be easy as bolt heads won't interfere with anything.
The two attaching the brace to the hood will need to little thought...maybe grind a carriage bolt head flat, file the hole square and install a nut on the back side (I don't know if you have room for this...never done it) or install a Riv-nut in the hood and grind a round head slotted screw down after it's installed to look like a factory rivet...
I think the bolts are 5/8" long but 3/4" may work, just check the depth before installing to be sure you don't touch the top of the hood when tightening them up.
