Agree with Don. This is a standard deck and it's the staple deck of a client, you can't mess with courts like a KS project. Card historians have noted the strong traditionalism people attach to their cards and how designs change very slowly through the centuries. It basically boils down to these two reasons:
1. Gamblers are notoriously superstitious (they have to be, just ask any mathematician). They will blame any loss on any changes to their cards. Some gamblers have favorite decks down to the brand, number, year of production, etc. Faro players, for example, still played with cards that had sharp edges, single faces, no corner indices, decades after everyone else moved on.
2. People play with cards that their family or friends play with or what they've seen on TV. They don't want to be the odd one out. They won't play bridge with grandma with an erotic deck of course. Kids of a certain age get precocious and want to play with cards that adults have, they've started to think their Disney or Marvel heroes deck are too childish. Then they grow up with the familiar courts and it becomes culturally ingrained.
When it comes to club decks or house decks, there's only so much you can do. Stick to Don's suggestions. People pay more attention to faces and items than clothing, since they're more abstract and it blurs in their memories. I can recall the suicide king's face but if you swap his belts or coat with another, I probably won't notice.
