Front hubs are front hubs, disc hubs are no wider than normal hubs. You could use this wheel just fine provided you put a different front brake on the bike. Thankfully most modern front hubs are all spaced at 100mm, so considering your bike has disc brakes now, that means it's modern and this would work fine.
Personally though, I'd build up a disc brake dynamo wheel if I were you.
