The trouble is performance. N64 emulation is all software rasterization based, but it can be rewritten to use WebGL. It's just a lot of work that no one's done yet. RetroArch runs at 40fps because it can use SSE ops, which is beyond what browsers can do currently.
I think it would be possible to ship an Electron app with a local build of Retroarch, modified to export the rom's game data and selectively replace the draw calls with other ones. That way you can basically swap out starfox with mario, if you wanted. If any of this sounds interesting, shoot me an email (see profile).
It's already been ported to the web. https://medium.com/webmr/n64-vr-with-javascript-e188de42ced5
