I have to admit that I didn't know a thing about the specifics of goalie skates. Your idea doesn't sound too bad to me, so why not give it a try? You're bound to learn lots of things you never would have thought of. I used a pair of used ice hockey skate myself and ripped off the blades. The boots I'm using now are also ice hockey boots but they never had blades mounted to them. I bought them directly from the manufacturer, Fesl. I would buy some other boots now, however. Mine are too inflexible at the heels.
