Yeah, you'll need to make pretty sweeping changes to the number of giants - or change things to be a more "sneak" kind of mission. I remember that hall with like 20 giants in it... Not going to happen in BRP. Of course if you go with the BRP 'realism' vibe, far fewer giants can survive per square mile, so a really small clan of them is about it.

But in general you will need to take inspiration from any AD&D module, but not so much take directly, or else you'll just get chopped up PCs.

But this can be a feature not a bug - because of D&D's level-based advancement it basically requires throwing more of a foe at PCs, which dramatically is not really as interesting as fighting fewer more challenging foes. A BRP fight with a hill giant steading of 6 giants would be as interesting as a D&D fight with a steading full of 30 of 'em.
