Custom Civ Idea - Anglo Saxons

[Sire Stroud]

Hi, I'm planning my first civ - The Anglosaxons. I'm going to attempt to learn modding so I can bring my idea to life.
UA - Fyrd - +15% production in cities when at war
UB - Reliquary chapel - +2 faith, +4 tourism
UU - Thegns - Replaces long swordsmen. Slightly stronger, gains faith per unit destroyed.

Firstly, is the UA actually possible? Secondly (and most importantly) Is it balanced?
Thanks.
