On the topic of statues, I don't think the specific statues will make a difference, aesthetically, any more than engravings do. It's just an omega symbol unless you go out of your way to examine it, and if you do that, you'll realize that the decorations on your crossbow bolts (you dirty cheater) and the engravings on your floor are also of groundhogs and laboring and legendary cakes, so it shouldn't hurt. There's that moment of pain when you're actually placing the thing and the name is thrust into your OCD-contorted face, but I suspect it would be a simple matter to have the objects listed as generic unless you "expand" the list, in the style of cages.
And I for one would be very grateful to have a "commission" or "blueprint" feature in the game, where I could specify material, ingredients, artist and subject matter for a project without the stockpile shenanigans, material forbidding and savescumming that's currently called for in order to get an engineered result. If I want my best engraver to do the walls of the king's room with battle scenes and horsies, I should be able to write up a contract for that. If I want to make a suit of steel armor with sapphire bands, then there should be a way for me to order it. Maybe the craftsdwarf gets paid extra for the work, or he gets an unhappy thought from having his creativity stifled, or he throws a month-long party when he's done, or he goes into an egotistical mood and jacks a bunch of my adamantine to make a statue of himself that'll berserk him if I ever destroy or sell it. Name your price.
