Following the present DR system, all you need is a ship with the latest shield systems, but relatively light hull.
For example, Durandium has 60% of the resilience the default values (yamataium) offer. So a cruiser (base 30) armored in 'lighter' Durandium gets to 18 SP instead. It's shielding, by comparison, would usually be 30/3. So yeah, there are cases where the shielding is tougher than the hull overall.
