Got it! There’s just ⟨ᚲ⟩ for the phoneme /k/ (as in cute, kill, queue). Looking further you also doubled ⟨ᚹ⟩ for both ⟨W⟩ and ⟨V⟩, those look fairly reasonable adaptations.

Cyrillic would give you the opposite issue - too many letters, you’d need to “cull” some of them out. And looks-wise I think that Futhark rocks.
