Skateboarding

I am new to skating and would like to try to get more into driving around town, however, it doesn't feel safe yet doing it on my standard Bones 103A 52 mm wheels. Our general old European city has some rough terrain (wildly switching between asphalt, stone, small patches of cobblestone, you get the idea).

So I thought I'd try out softer cruiser wheels like the Bones Rough Riders (80A hardness, 56 or 59 mm diameter) for driving around town without breaking my wrist over a small stone again. I'd still like to keep the harder wheels for the skate parks, though, and carrying around two boards seems like a huge hassle.

So what do you think about getting the Rough Riders with a separate set of bearings so I can do a quick wheel change whenever I need to? Is this dumb for any kind of reason I can't think of? Should I go with 56 or 59 mm when I don't want to install riser pads (if even possible)? Do you have any other wheel suggestions for this application?
