The Holte could be improved, but the cost-benefit is a non-starter.
We had one opportunity to rebuild a stand unfettered by land constraints, but have chosen to extend it instead. If we had any serious ambitions to maximise capacity, we'd be building something equivalent to the Anfield Road stand, which would have added an extra 4-5k more than the current plan.
Getting up to 55k with that one stand would have made a hell of a difference. As it is, we'll be topping out at 50k + whatever any further 'bowl optimisation' adds for the next decade at least.
