Artwork Variety

Not sure if this belongs in Design Theory, so I apologize if this is in the wrong spot, but Publication or Prototyping didn't seem right either.

My game has cards in it, of 6 different suits (though it isn't a card game and they're not used as suits). It's kind of like thinking of Settler of Catan's card (Wood, Wool, etc).

We're going to for a humorous, fun feel for the game. My question is do you think it is worth it (from production cost and artwork cost) to try to have several different drawings on the cards. To keep them easily identifiable we would put a symbol for the suit in the corners (like a regular deck of card).

To me the benefit of this is we can introduce some fun drawings. Instead of playing a 'Staff' card, you have different types of Staff card (Staff of Wonder, Staff of Soggy Boots, Staff of Leaky Goblets (those aren't real I'm just throwing ideas out)). This creates a little variety in the game, and gives players something else to laugh over and have fun with during the game.

However, is it likely to up my production costs dramatically? More so than might be worth it? I'm a very creative, whimsical person, my partner is very number and fact oriented and we can't see eye to eye on this. He says I'm "frivolous" I say he "hates fun".

Does anyone have any experience that might shed some light on this debate for us?
