The main problem with growing sprouts in raised beds is that normally the ground isn't 'firm' enough. They do much better grown in ground that hasn't recently been cultivated. They are also large plants so will take up a lot of room. At a minimum they will need staking to stop them falling over but you may find the sprouts 'blow', which means that they don't form tight buttons.
Caulis are the hardest of the brassicas to grow, they won't tolerate any check in growth, need very regular watering and ideally the soil should be limed too.
On the plus side peas and beans are great crops but I would have grown root crops like carrot,beetroot and parsnip instead of brassicas.
