I would not be wasting my money, I would be hiring you for all the other skills and experiences you have, which I would find far more compelling than whether or not you already know something you can learn in a few months. If I thought it was a waste to hire anybody who would take non-zero time to learn the stuff they need to know to be an effective employee at a specific company, it would be impossible to hire anybody (except people who already worked there and only left quite recently). Hiring full-time employees is an investment in their ability to contribute net positively to the company over their whole tenure, not in the first few months. You are right though that I wouldn't hire you to lead a dedicated front-end team. But I'd prefer not to have such a team to begin with. But I'd be happy to hire you[0] to lead a product team working on a product that requires a front-end to succeed. Either other members of your team will know how to make that part work well, and I would expect you to learn quickly from them, or I would expect you to figure it out and then teach the rest of the team. [0]: I'm using "you" as a stand-in for someone with your experience, who is otherwise a good fit for the organization. I may well not hire you in particular and suspect you would not take a job from me in particular, since we clearly have very different philosophies on specialization vs. generalization and investment in employee training, such that we may not enjoy working together :)
