The F-15 would be a good analogy here, I guess. The dogfight versions (e.g. F-15 C) are single-seater (with two-seater training versions), the strike versions (e.g. F-15 E) are all two-seater. The overall airframe was changed quite a bit for the strike version (mostly on the inside), but it's still clearly an F-15.
IMHO, the Apollo could go the same way, with a single-seater dogfighter (for everyday use) and a modified two-seater strike version, as seen in the intro. A two-seater dogfighter could be used for trainings.
Will there be some more detail on the body of those intakes? They look a little dull right now.
