It is possible, even easy. However while easy it requires huge amounts of self motivation, and persistence. Also biggest trap in indie dev are new ideas in middle of creating game, they usually drift original; concept into new areas, or make me create new project. This way i have multiple games started, while finished only once some kind of vertical slice.
There are multiple great plugins that help, also blender, houdini, quixel substance painter, all those apps are great for small indie teams. Automate as much as you can.
But if you can get some other person into team, do it, and you both need to pressure each other into being active. Do at least one task/thing a day for your project, no matter how small, just add something.
