Since you have the rims for it, go for it. All you need is the tires and valves and tape. It's not going to cause a crisis if it doesn't work and you'll still have your other tires if you go back. It's not more difficult but it's different. You flat much less on the road compared to a similar tube tire. (Maybe not a Marathon Plus!) But you need to remember to either check the level of sealant or just add some periodically.
