I think the closest your gonna get is that 325 thunder ranch. The 45acp and auto rim in the revolver is easy to get 45 super or mild 44 mag. With the rail you can use a light an laser when you want and I think night sights are possible. There are laser grips also. If you went with a 45 colt mountain gun you could get it cut for moon clips and run acp also. Here's my last wild idea (for this thread) get the 325 tr have a 45 colt cylinder put in that's cut for moon clips but I don't think it would work cause the 325 tr uses a short cylinder.
