Aaaay, whut?
Is this a metaphorical question? If so, it’s generally a bad idea to mix your metaphors. You can lead a horse to water, but a pencil must be lead, if you see what I mean.
If you seriously believe that black sheep TURN INTO goats – no. Not even slightly possible.
They’re different genuses – Ovis (sheep) and Capra (goats) – which means they’re like taxonomic cousins. They can interbreed, but it’s rare, like human cousin-marriage. But a sheep turning into a goat is as likely as you turning into your Cousin Kevin.
