if they like acidic soil, would it be useful burying a couple weeks' worth of coffee grounds in the raised bed

I've read that used coffee grounds don't have that much acid in them, because it comes out in the coffee. If this is true, you'd have to use raw coffee grounds. Pine needles are also excellent. Not sure about needles of other conifers.
Here's a thread on another forum about making acid soil for blueberries.

what about those floating islands like they used to make in Mexico (the name is escaping me, and since I'm inside on a quick break I'd better not take time to look them up)? Could do the hugelkultur thing on top of those little islands.
My thought is since blueberry roots go 12-18 inches deep i want that much top soil and then woodwaste for another couple feet under that, i have some worry about the wood waste retaining too much moisture and causing root health issues with the blueberries and have considered increasing the soil level to provide abit of safety but then again its a raised bed so maybe that worry is unwarrented.
Thanks in advance.
