That will be doable, but that type of oil slick pattern is usually incredibly smooth and reflective. If chips are that smooth, they're going to be very slippery and not stack well. You can try and emulate the pattern, but the more they rub together you'll usually lose a lot of that shine. Just some food for thought. Welcome!
A good use might be the inlay/label; the sticker on the inside of the chip. Lots of them have a recess to put a label on, the label could be shiny/oiled, whatever works, that shouldn't affect the stacking.
And many of us like chips with different colors to differentiate between the denominations; if they're all entirely oil slicked, even if its different colors, they will get mixed together and create "dirty stacks". This will make them very impractical.
