won't that ruin the legacy standing?
That is only true in the sense that you won't get the in-game achievement messages on time. Like, you'll get the 10-generation achievement message at the 11th generation instead.
Otherwise the way you structure your legacy is completely up to you and what you think is fun ☺
If you're looking for a more structured ruleset, in addition to what was suggested above, there is a very popular legacy challenge created by Pinstar which can be found in the first post here

And the entire stories/challenges/legacies board in our Creative Corner is a good place to find lots of other challenge and legacy ideas.
