Without getting a degree [or not being a natural Leonardo daVinci] you’d realistically stand no chance of getting a true industrial design job - but there is a growing need for new business development within consultancies and most are picking up dedicated business managers to handle that task. It’s not designing, but it can be a position that works very close with and can complement the goals of a firm’s ID function.
OR, if you take the plunge and dedicate the next 3 years to a solid, well rounded ID program your business degree will be of great value both while you’re earning the ID degree and after.
