Lol you know what's funny.. We home school our kids and when we tell people that we do, it perplexes them because they try and fit how schooling is traditionally done and try to make it fit with the concept of home schooling and draw a conclusion that it cannot/shouldn't be done.
But it requires a whole new train of thought because that's the whole point to home schooling, that it's not school. Same people may try run it like that, however you go forward is up to the family and this is very similar.
You can't really take the traditional means of how we gather and apply it to meeting in the home, it requires a whole new train of thought and understanding of the saints gathering. Obviously if someone wanted to organise a gathering and could host 20 plus they would. If someone wanted to and could only do 5,6,7,10 they would. The point is gathering and fellowship of the saints where a meal is shared, someone can share a word, receive prayer, help each other, laugh with each other, sing together, mourn together, grow together, live life together, be together.
It is totally and utterly different to traditional means and try to draw conclusions between won't work.
Doesn't even have to be in a home, why not a cafe, restaurant, outside somewhere? Anywhere!
