body man here.
yes that hood can be repaired.
they have tools that weld special studs on aluminum panels to pull the dent out. there are also tools to glue tabs on the hood and pull the dent out that way. either way is done all of the time in bodyshops.
on the edge they will straighten the edge and then they will probably aluminum mig weld up the rip.
after the panel is roughed out they will use a filler that is made for aluminum to finish it off.
find a body shop that actually has these tools and it will be a simple repair.
aluminum is getting common place now but there are a LOT of body shops that aren't equipped to do repairs on aluminum panels.
