C1 focus: Choose this form for the intended meaning and discourse effect; nearby alternatives may be grammatical but can change viewpoint, scope, time reference or register.
Formal register
Conditional inversion is strongly associated with formal, literary and rhetorical styles.

C1 takeaway
Do not ask only “Which form is grammatically possible?” Ask what the speaker is presenting as background or foreground, completed or ongoing, certain or tentative, generic or specific, neutral or emphatic. Advanced grammar is the control of those choices.
