Sometimes we feel a sense of obligation to finish it as the quilter intended- I know this because I inherited approximately 12 WIPs from my mentor. However, I came to realize that the original quilter would be pleased and honored to have you finish the project YOUR way. I would use 25 of the blocks to make a top, use 2 on the back, and keep the batted block as an accessory wall hanging. Best of luck with the project!
