Alpine look for reinforcements: Who could be in picture to replace Ocon?

Esteban Ocon's marriage with Alpine lasted five seasons, but it will come to an end at the end of the current year. While Ocon is in the picture with Haas F1 and Audi (now Sauber/Stake F1), the French team are obviously looking for a new teammate for Pierre Gasly - at least, it is expected that he can stay on. For the second seat, Alpine do not seem to rule out an unconventional choice by any means.
