Is this close to the paneled look that you like? It was made for me some years (and pounds) ago by Master Domingo who was of course partial to the Charles V influence. This is one of our dancers borrowing it for the first time. Cod pieces take a little while to get used to.
Yes, you can make most of your own armour just like I did. I expect you to actually be able to do better with some fluting and a deeper dishing stump. I used leather strap articulation which is extremely simple, flexible, and I stole it from a set on display at Schloss Langenburg near where I lived in Swabia. The tasset lames are all the same. I usually start newbs off making a set of pauldrons similar to these just for general skills practice. You just need some simple tools like a sabre saw, drill, hammers, dishing stump, anvil/I-beam/RR rail, file, leather awl, some rivets, and sheet metal. The rest is just finishing work.
