From an Android App Bundle, you can generate a "universal APK" using bundletool build-apks command with the --mode=universal
flag. This will generate a single "fat" APK that is compatible with all devices (that your app supports).
I know this isn't strictly answering your question, but trying to merge the APKs is not only a complex task, but will result in a lot of cases in something incorrect.
