A solid cast steel hilt would be tough, but there is always a way.
I have a friend who does steel sculpture. He welds small bits together to make big ones. You could do the same with a khuk handle...starting with a piece of steel gas pipe, say...and adding other pieces to fill out the shape roughly. Then a long session with a grinder, files and sanding to give the shape and finish you desire. It would be a lot of work, and heavy, but it's do-able if you have the determination.
Look around Maumee for a welding shop...maybe the auto shop at your local High School. It may be possible to enlist the help of students, or even the instructor. I've accomplished similar projects in this way. The secret is to ask nice, and get the helpers involved and interested. Every metal shop I've ever been in has a scrap box full of 'parts' that can give you ideas.
