That is a shame because her house has hardwood floors and good acoustics.
Maybe the hammers sound softer because they are still wet? At least it could be an attempt (after consulting a local expert) to put the complete mechanics out of the piano, that is very easyly done. And to let the hammers dry out that way because outside the still wet piano it dries better (maybe with help of a fan). On the other side it is maybe not good if it dries too fast. Nevertheless perhaps something can be done without spending too much money.
I have an old upright in my holiday house, and transported it on a car trailer with a cover. Unfortunately there was a gap in the lower side of the cover, and the rain during the transport went through the complete trailer, and I needed to drive for 6 hours. How was I pleased that after removing all outer parts of the piano, and whipping all water away, this over 100 year old lady seems to have survived that trouble.
Maybe the costs for restauration are less than you think, and Yamaha is a quality label, every part should be able to be replaced. Hammers can be replaced regardless which brand. The facturer get some hammers and produced it after that. A complete set of new hammerheads cost some hundred dollars, but the piano needs to be intonated again, what costs much more than new hammerfelts, unfortunately.
