<div dir="ltr">I'll let the pros answer, but by my math, a 6.25mm
hole would be required to give you a 20mm wide copper

via, maybe a 3.2mm hole would be enough. Dunno if that's
practical, though.<br>

Or a lot of little through-vias -- typically a field of them spaced
about 0.05in (1.25mm) apart.<br>
