Related patterns
Similar
Same ばかり base, different force — ばかりでなく just adds a second member to the set, while ばかりか marks the second one as the bigger surprise and normally needs も／さえ／まで to carry it (謝りもしなかった).
ばかりか keeps the first item true and piles a bigger one on top of it (遅刻したばかりか謝りもしなかった); どころか throws the first item out as far too small or plain wrong (謝るどころか責任を押しつけた) — ばかりか cannot carry a contradiction, どころか cannot carry a plain addition.
Lookalikes
Adding か flips the direction — bare ばかり restricts to lopsided repetition (ゲームばかりしている scolds the narrowness), while ばかりか opens the count upward and always expects something further to follow.
