Going back to the original question: Your problem is you don't have a 110, or much experience of it, so you are thinking of it and it seems the case is "the grass is greener". Truth is, the Disco is a pretty good all rounder, it can kinda 90% effectively (its a bit slower, heavier, etc) do the job of a reasonably comfortable car, and it can 90% or so do the off roading bit that a 110 can do. So its a pretty good compromise.
ALL cars are a compromise, once you factor in the wide range of driving conditions including off roading of various severity, and towing etc.
Buying 2 cars - it gets round the compromise, you have the use of both and can choose one, that particular day. However, if I were to own 2 cars, I'd have them sufficiently different so they can do different things well. 110 and Disco 2 are quite similar, for example compared to a Jag saloon and 110, or a small diesel supermini and a Unimog; or a hot hatch and a Discovery.
Can't really add much more since you've already been given decent advice - try to get an extended test drive of a 110.
