αἰεὶ κινδύνῳ θῦμος τῆς πολλὰ φιλούσης ·
ἂν ῥαίηται κη?', ἦν φιλέοιτο σόος.

Should I have the last word be σόος (for θῦμος) or σόη (for ἡ φιλοῦσα)

Are you using κινδύνῳ to mean “in danger” here? I’m pretty sure you’d have to phrase that idea differently. κη?’ is κῆ??

And is ἦν = ?άν?

Yes. Yes (sorry for forgetting the accent). Yes.
