This can work if the block doesn't contain triangles. It does add a surprising amount to fabric requirements, and makes the quilt heavier. Can be a problem is you decide you want to quilt the traditional 1/4" outside each seamline.
It's better to just practice until you are consistent with 1/4". Are you trying to sew without a seam guide? I use a strip of moleskin carefully positioned as a "stop" for my seams. Trying to use a tape mark or 1/4" foot (often inaccurate) does not work nearly as well for me as the physical guide.
