you can use it- many of us use plenty of mixtures of fabrics in quilts that turn out great- pre wash all of your fabrics- and it will be fine-
lots of blends make wonderful quilts- even paired with batiks,
flannels
corduroys
calico's
homespuns
wools
and even silks
i would use a good quality poly batting- like dream poly- or even hobbs 80/20
no reason not to use the fabric if you like the fabric
