Based on other companies which tried and failed (e.g. Spoonrocket, Sprig) this seems like a risky model to follow. It's possible that the costs of managing such a kitchen plus delivery service is at this point more expensive than brick and mortar, or the margin earned on these deliveries is much less than sit down customers.

Maybe once kitchen automation technology gets there this can be a workable model.
