To my mind (having not been around at that time) vintage to me means whites, off whites & creams with laces the same colourings. A crazy quilt in these fabrics I think would be ideal, and yes it would take longer to decorate the blocks with some embroidery, in the same colours or pastels, but it would look fabulous. It needn't be mind-boggling if you cut 12" squares - as many as you can cut at once - 3 or 4 times (stack&Whack). Of course, if you don't do embroidery it might be a challenge, some could be done using the machines' fancy stitches, lace ,braids, or you could choose to not have embroidery at all. One of these is near the top of my bucket list .
