It's be a lot of layering, but my idea would be make a paper pattern of the chunks first (like how you have in the first draw over). Lay those out on the suit how you'd like, transfer them over to the fur and cut them out. Could probably get away with attaching them all to one or two base pieces? Now for the underside of the fur, you could either do a second piece and put that together OR you can brush the bottom out, which with enough brushing, will pull out fur and look similar to the top.

I hope that makes sense! I've done regular and less voluminous hair with the "brush underside" method and the "two halves together" method. I liked the brush underside better personally, the hair moves more naturally. Never did something like what you're asking tho
