I agree with Helios, I like to see a yellow Daidaimaru as well. Honestly I would be all in for an yellow Orange Arms-remold. Because while Mango works with the cape, nothing else does. Especially not the chest piece, the shoulders and the horns.

I would rather see a mixed arms using existing parts, like Yomotsuheguri.

Give him the headpiece of Orange with a remolded head crest (maybe make it look like a small crown), the chest- and shoulder-armor of orange without the bumps and with insignias, maybe remold the shoulders for a more western look. Add the cape from Mango, done.

Daidaimaru works IMO because it only resembles a generic short sword, the curved blade is a hint to a slice of fruit rather than a specific Japanese sword so it still works. Or give him two remolded Sword Bringers from Golden Arms.

I can see this working well. I just hope they don't get lazy and reuse the existing Duke-suit without changes. We need a proper de-energized version, I would love to see a downgrade that is as significant as the change from Melon to Melon Energy.
