28 hole hub shell is part of the narrow axle'd wheel on my Brompton, folding bike.

for a bigger wheel , and more spokes , but still wanting a narrow over locknut distance

a mix and match approach is mechanically straight forward,
it involves opening up the hub itself,

replacing the axle and sun gear (one piece), and indicator chain.
[different for the shorter right side]

or buying the shorter axle'd hub, and changing the hub shell.
