If the fabrics you are using blend well together, I don't think it would be that noticeable.
Another thought is this... OBW's for instance, are sewn using a new technique that eliminates Y seams. This technique does not lose points when being judged :wink: So if you piece this well, why would a judge take away points because you eliminated a triangle piece in this block?
The quilting you choose may also cover this area and make it less noticeable too :D:D:D
