Pevensie's' age in HHB vs. LB?

[StBrianofMinneapolis]

Does anyone have any reasonable insight or evidence to compare the general age of the Pevensies in the Horse and His Boy to their Narnian age in the Last Battle?

I had some general impression that all the kings and Queens were of a twenty something age in the Last Battle, and somewhere close to that in the HHB. This is just an impression, but i always figured Lucy was roughly 20 years old in HHB.

I'm actually trying to use this to figure the order of which movie should be shot first. I realize we are all in movie franchise limbo right now, but it is still fun to think about. All the actors seem to be approaching that mature age for the kings and Queens anyway.

I hope in HHB Lucy is portrayed as an older 16 and close to 17. Edmund as 19. Susan as 21 and Peter as 22.

In LB IDK, 20's is good.

I think the Pevensies are older in HHB than in LB. However if they change that due to the order they shoot the films in, I don't think I would really mind.

Me neither, they will probably look the same.
