I have what I *think* is a katsura in my garden. It is beautiful - lovely weeping habit but with branches way above head height. Small round leaves, which go a gorgeous buttery orange in Autumn (September, usually) and make fab leaf mould (I am slightly obsessed with leaf mould). It was in the garden when I moved in 15 years ago, and I am still trying to make a positive ID! However, I am in London - I believe they don't thrive well in very cold, exposed sites. If I had to replace it, I would probably go for a Liquidamber - Rowans are pretty but a bit too small for me and they are being planted all over London. I am sorry you lost your honey locust, there are a few in neighbouring gardens and they are absolutely beautiful trees. If you can establish why the old one died and ensure the problem is fixed, I would replace like for like!
