I also think they would add a new dimension to the campaign, threatening Narnia from the north west.
There is little mentioned of the Telmarines arms arms and armour, though it would appear to be somewhat similar to the Narnian nobility's (of the western european feudal type. I would say that they would need a lot of men at arms, archers, spearmen and heavy cavalry. I would try to avoid "knights" as such, but go for more fuedal looking cavalry and infantry. There is no mention of mounted knights in the books, though horsemen are mentioned. In fact any fighting seems to have been mainly on foot. The narnian humans in particular would have fought mostly on foot.
The Calormenes are noted as riding through the desert, but then when the fighting starts they are on foot. This is unusual. Personally I would model the Calormenes, "seljuk" in their appearance and as mainly light cavalry, with cataphract types for the generals. I would also include some spearmen, swordsmen and light skirmishers.
For Archenland, I would give them better cavalry than the Telmarines and Narnians, including horse archers, but lacking in spearmen and infantry. They are after all a mountain/steppe people and in the book The Horse and His Boy are noted to be mainly on horseback.
To summarise using MTW1 terms:
Narnians = Unique, though with royal cavalry similar to the catholic factions
Narnians of the Empire of Jadis = Unique
Calmormenes = A very "Saracen" faction, like the Turks, with equivalents of Saracen infantry, Turcoman Horse, Foot Soldiers, Ghulam Cavalry and Khwarazmian Cavalry etc.
Telmarines = Like a an early era Catholic faction, with a very Norman feel about them
Archenlanders = As above though with better cavalry and horse archers. Slightly more eastern or byzantine in their appearance perhaps.
