Lego watercolor painting

My wife has started learning watercolor painting and we came up with the idea of painting Lego 😀 She's looking for a side hustle and this could be both fun and useful. I'm writing to test the market - would anyone be interested in something like this in the form of a picture/gift card/etc. based on your Lego set picture/photo? What do you think? This is of course only first attempt at Lego and she needs to develop a technique to capture it as best as possible, but we just want to know what do...
