Can I sell merged actors based from marketplace?

I’m new to Unreal so I may have a misunderstanding of how some functions work. What I am wanting to do is build props, and sell them on the marketplace. For example:

Lets say I build a house in Unreal. I then download a pack from the marketplace that has furniture, and use it to furnish the house I built. Then I merge all the actors. House, furniture, everything. It should all become a single asset right? I know I cannot sell anything containing the furniture itself from the pack, but the the prop should no longer contain any of the furniture assets from the pack because they are all a part of the house now. People shouldn’t be able to take any furniture from the house, because it is connected.

Please do correct me if I have a misunderstanding on how the merge actors function works. Thanks for any help.
