Your question doesn't on the face of it make a lot of sense. Presumably if you have 1200 hours of wide body jet experience you would already be working for an airline ? That represents around 2 years experience in most companies. I would have thought with a reasonable level of experience in airline flight operations ( 2 years sounds reasonable) you would be in the running. Of course if an airline stipulates a higher requirement or a more specific requirement that is their right. It may well be a stipulation their insurers impose or a level of experience they require themselves.
In any event you can only apply and see what happens, the worst is they will say no.
