If you can do a baby quilt, you can do a queen. A queen is nothing more than 4 baby quilts together. There are quilt as you go methods, which make the quilting easier on your regular sewing machine. You will not be bored making the larger quilt, especially if you do a sampler or another quilt pattern with multiple block types. And you can always start the larger quilt and periodically switch back to do a baby quilt. No one says you have to do the large quilt all at once.
