When fabric does not have the appropriate weight and 'hand' to start with, it would be better not to use it and find another fabric. When you try to make it work it usually involves more cost and less success than just using something more appropriate to start with. Fusible interfacing has its own set of issues. When you press, which you will obviously be doing, the fabric will shrink differently than the interfacing and cause a 'bubbly' look. Guess how I know.
