While a larger heatsink is nice to have, there does come a point where you don't get much increase in cooling performance. A heatsink can cool only to ambient temps and as the delta between the HS and the air gets closer, cooling rate slows down. Besides, these ESCs being anywhere from 85% to 95% efficient means that not a whole heck of a lot of power is being wasted as heat TBH. Just doing the internal mod and adding a little extra heatsinking to the Quark goes a LONG way to improve its thermal performance without sacrificing size or weight.
