Just... No.

See Phineas? His mother and Ferb's father are married. Phineas was born to a totally different family to Ferb. Get it? The only way they're related is because Phineas' mum and Ferb's dad are joined in Holy Matrimony. BY LAW. BROTHERS. BY. LAW. No blood relation. They aren't related in any way, shape or form. It's only in law.

SO. Technically, they're not cousins. Like AT ALL.

Sorry for being so harsh; that's how I get my points across. :) And I love Thomarie, so thar's another reason fer ya. XD
