It's not lunacy. With revolvers, the Achilles heel is capacity, with an additional limiter of slow reloads added on, just to add insult to injury. Carrying several of them is a good solution, if you care to deal with the resultant weight penalty.
Were it me, I'd be looking at carrying one on the strong side hip, and one on the weak side. If you're already wearing a gun belt, hanging another gun off of it is no problem. If you're already wearing a cover garment, it'll cover both hips as easily as one. All you need to add them is the second holster. It also gives you a gun available to either hand, in case one is occupied or injured.
A close second would be one strong side and one cross draw. The cross draw makes the secondary available to the strong hand, as well as the weak. It gives you an easy gun to access while sitting. It really turns the second revolver into a second primary, rather than a traditional BUG. The disadvantage is that they can be harder to cover.
A third option would be a double shoulder rig. They actually work better than a single rig, as the load is more balanced. They only work well with certain body types, though, and can be obnoxious if you don't like having straps bearing on your shoulders all day. After all, you wear a belt anyhow, so that can be easier to learn to live with.
Both the guns you've picked are fairly bulky for their payloads, but that bears fruit in their shootability. A four inch gun is still plenty carryable. Just look at all the people packing commander and government model autos. When I was young and broke, my first carry gun was a police trade Model 10, with a four inch bull barrel. Made the long midnight shifts at the gas station much more comfortable.
