Such a mount could be made, no problem. Here is the problem I see. This is a small mounting surface and by extending a mount out from it you would be adding quite a bit of leverage should accidentally drop or hit it. The second thing would be that these dovetails are not made to have things inserted and removed on a regular basis. They create a tight fit by the friction created by placeing a slightly oversize dovetail in the slot.I would be afraid of wearing pretty quickly by removing the mount repeatedly to the point it would not fit securely in short order. So my idea is this. Could it be done, absolutely. For a permanent fixture it may work? I do not believe from an engineering standpoint that it would be a good design.
