We just moved into a new home, where all the bathroom sinks have the Moen 4621 acrylic teardrop shaped handle. Both kids and elderly parents are having trouble using the sink now (handles are hard for them to use). Is there a way we can replace just the acrylic handle with a lever-style handle kit? (I see that Moen has a 4621 model: https://www.moen.com/products/Moen/Handle-Kit/150625). Just don't know if it's possible to replace, and how hard the replacement would be. Thanks!!
