The purpose of boot.img is to load kernel + initrams so that it can mount a LUKS file-system on other media.
It's not too difficult to make a small boot.img with initramfs with docker for single purpose applications e.g. PiHole / Homekit but I think you would be better off going down the LUKS route with an image built using rpi-image-gen and provisioned using SB provisioner.
