It can be remedied by lots of basting; however, I personally don't think the process is worth the time it takes.
I've been quilting long enough that I don't consider myself to be a "non-quilter" but I prefer polyester batting because I like the poof of it. I usually use the low-loft though. I'd think the high loft might be too "poofy" to quilt with your DSM though and not get frustrated with the bulk of it. I have done both machine and hand-quilting with polyester batts. They are very easy to work with and do well with laundering. I did use a cotton batt for a Grandmother's Flower Garden simply because of the vintage feel of the pattern. Hand quilted it. Glad I usually use poly!
