What to do to make an Adhemar le Puy

Bishop Le Puy, what did he look like? 

How can you make him from existing Perry miniatures .

Well what have we got to start with ?

A mounted abbot, a bishop on foot and a variety of heads from different figures.

Apparently Adhemar did fight/ aligned himself in battle and at one stage carried the "holy lance" into battle.

This is not a contemporary illustration  but it does show the bishop carrying the "holy lance",another near contemporary illustration below shows the Bishop on his death bed with almost identical  headgear.

Other references to use could be Bishop Odo in the bayuex tapestry , this might give us an idea of what a bishop would look like in a war zone.
