Can shading only be removed? (Photo)

I got the first portion of this tattoo (the two bottom roses/flowers) back in October and loved it very much. I had the additional top 2 roses and buds added last week. The top two roses are MUCH darker than I wanted them to be. I like how the largest rose is lightly shaded. Would it be possible to just have the dark shading in the petals of the top two roses lasered a bit so that they match the shading of the bottom roses? Every time I look at them they are just TOO DARK and it makes me sad. :(
