Mulitple media upload inside a repeat

Hello :)
I’m a developer. Is it possible to make a repeater item with media type field (custom made widget), then allow a user to select multiple files, so the repeater fields would automatically add repeater items with corresponding files?

If not, is it possible, to somehow add a working ACF repeater inside a widget?

Any crazy solution written in php/js, can be with ajax, promise, mutationobserver, or anything, appreciated.
