You might have to experiment to see how the end result looks .... do a minimum of quilting on it then after quilting, fuse your fabric choice over the quilting. I suspect that unless you use a fairly thick fusable and fabric ... the quilted lines will still show through even slightly.
An organza overlay (not fused ... just laid over it) might hide any quilted lines and give a nice shimmer effect as well (the shimmer effect overpowering the background and any quilting lines).
I think you have some experimenting ahead of you
