I do not know why you are getting downvoted, it is a great idea. But it is very hard. To run an instance 3 things are crucial, 1. Time, 2. Money and, 3. Expertise. You need money to buy/rent servers, expertise to run a server and time to manage an instance, like moderating, defederating with other harmful instances, communicating with admins from other instances etc. There are a few south area specific mastodon instances, there was one pixelfed instance, but never a lemmy/mbin/piefed instance, at least not any I know of.
