Yes. I think I’ve even seen this implemented.

Certainly some drive-in theaters in North America worked like this. There would be signs telling you to tune your car radio to such-and-such frequency to hear the film audio. Here’s a picture of one: https://c2.staticflickr.com/4/3186/2718300357_ec1b9f3f45_z.j...

Yeah, this is totally doable with walkie-talkies. The biggest drawbacks I can identify would be audio quality and interference.

Within a distance you can walk, it should be pretty easy to find a band with minimum interference even in a crowded metro. Also, quality won't be as much of an issue as range. There are pretty low limits on how much power you can use on the FM bands without a license.

Source: I drove all over a crowded metro in the early 2000s with one of those fm transmitters for playing audiobooks to my shitty car stereo. 3 station presets was enough for the whole area.
