Can I use Origin-based base game with ZLOrigin-based packs?

Hi, I have a question. 

I just downloaded the free base game of The Sims with the latest option to legally download it for free from the real Origin. I have all the packs installed through ZLOrigin (minus Strangerville). If I wanted to use my legal copy of the base game (so I can access the gallery) with the cracked packs, could I do that? If yes, how? 

Yup, without zclient launch origin

Could you explain to me how I would have to do it please? Thanks! 

Launch origin, then launch your official game.

Remove origin from task manager if you want to launch zlorigin. Otherwise it can be messed up.

If you want to play zlorigin sims, launch zclient, and run the game from there.

You cant use packs which you dont have in origin. Installed not means you have it.

just use the tampermonkey add-on for your browser, then install the script that allows items from the gallery to be directly downloaded to your PC. Then you just add them to your tray file (or mods folder if you're downloading something other than lots/rooms) as you would normal mods.

Tampermonkey: http://www.tampermonkey.net/ (click on the tab that matches your browser)

Script: https://anadius.github.io/sims-4-tools/gallery.html (click "userscript" link, do not do this until tampermonkey is installed)

Then go to the online version of the gallery (https://www.ea.com/games/the-sims/the-sims-4/pc/gallery) and when you click the "add to my downloads" button, it will either auto-download to your PCs downloads folder, or it will open a separate page with a simfileshare page with a direct download button. No ads on any of this, either, btw.
