SMT inductors with large pads for heat transfer?

We wish to heatsink our SMT inductor pads by thermal via’ing them down to bottom-of-PCB layer copper, and then using thermal transfer stickers (or some such thermal conductove transfer medium) to transfer the heat to an under-PCB heatsink. Therefore, we need SMT inductors with large pads. The inductor is 1uH and i(peak) = 20.5A and I(rms) = 17.3A. Ripple is at 200kHz. (Buck converter).

Do you know a family of SMT inductors with such large pads?
