Can you just safety pin it to the back? Like 3 pins would do.. But this would poke holes in the whole thing.

I suppose that's possible, was really hoping for something that would not damage it. Or If I AM goiing to damage it, being able to easily undo and redo it would be ideal, on the off chance I decide it's in my benefit to wear a hood. (Like perhaps a button on the back of the hood and the back of the jacket. )

Tape it down when you fold it inside, maybe that'll work.

You could find a local seamstress or leather worker. Have them cut the entire hood off at the seam, rerun the main zipper, run a new zipper or set of buttons around the collar, and probably a set of buttons up the front of the hood. Then you have a nice jacket with a closable detachable hood.

Some strong Velcro tape maybe?

How much do you really need to ride in the rain? If you're cheap, just get those cheap rain jacket/suits. They work decent and you won't care if they tear, or burn on your pipes. If you want something better, then get an actual motorcycle rain jacket/pants/suit. You don't need a high end one if you aren't traversing the country, rain or shine. And they'll be purpose-built for forr motorcycling, ie: the designed for riding position, over jacket, room for gloves, etc...
