I think it is unlikely that the 'new' livery will ever be more than painting out the BA logos and slapping on a Flybe as in the pic. Some of the ex-BACON fleet will be gone in a matter of months, and the remainder phased out over 3 years max. Doesn't really make economic sense to go through a costly repainting programme for such a short period of time in service.
It might not be terribly aesthetically pleasing, or good marketing, but Flybe management sure do keep a tight hold on their cash. They won't part with a penny if they don't have to.
