Should I use a shopping cart icon?

We have a website that provides downloadable items for users. Those downloadable items can be found under different articles and series. So not everything you might want to download is on the same page.

That's why we have an 'add to download list' feature. If you use that feature, everything you've added to your download list can be downloaded at once.

Since this works exactly like buying items on a webshop, I was wondering if it's a good idea to use the classic 'basket' or 'shopping cart' icon. Even though you can't buy anything.
