This has been asked in some form a couple of times in the past.
Though I would like to add some arguments why this should maybe taken as a serious request.
I get that Linux does not seem like a typical target platform for mechanical engineers but especially Fusion 360 touches an audience that may have previously not engaged too much with mechanical CAD at all but has now embraced Fusion 360. I know from personal experience that at least in my industry many colleagues have and that the wish for a Linux version is much bigger than one might expect.
I for once use Eagle professionally at work a lot and the interconnection between the tools is a super exciting feature but the fact that I have to boot a VM for Fusion is a huge hurdle in the workflow.
A lot of my work revolves around Linux for various reasons, one being f.e. that all the good open source software for working with embedded systems runs best or only on Linux, so using Windows or Mac professionally would never be a serious option for me.
I'm sure people of other professions who might not immediately identify as mechanical engineers are also profiting from a good and lean mechanical CAD tool in their work and might already do but also boot into a vm or dual boot to run Fusion at the moment. Just think of all the people doing research. Any scientific research that takes place in the physical world profits from easy and rapid physical prototyping. The success of desktop 3D printing and desktop mills like the Bantam/Othermill in this areas is proof enough that there is a large demand for this. On the same side a lot of researchers utilize Linux in their work because it makes their work easier or even possible at all.
Now the interesting thing is that the support for Fusion through Wine is actually very far already. There are mostly rather minor things that keep it from running flawlessly. I would never expect Autodesk to write a native port from scratch, unless your toolchain would offer an easy path for this I can't imagine this would ever be profitable for you.
So I want to suggest that Autodesk might approach Codeweavers to do a full 'port'. Codeweaver does this as a commercial service and they are largest maintainers of wine and have made windows software work for a lot of large enterprises in the past.

I have no affiliation with codeweavers other than that I am a user of their software Crossover.
I hope you give this a thought and at least get in touch with them.
