Can you suggest a 5 speed hub? Sturmey Archer?
I'm guessing with the 5 speed, 3 is the direct drive and I will have 2 lower gears and 2 higher gears... Is definitely better than just direct drive and 1 higher gear...
Sharing a story... (a short version of the story) Yesterday we helped an old man with his old rusty bike (he needed some tools) and he wanted to try my bike. After he used it he kept talking about brakes and he told me I needed a front brake. Then he took his backpack and he had two weinmann calipers type 810 and brake levers and he just gave them to me. He told me the levers were broken but I fixed them. This morning I add the front weinmann caliper and is working very well. I guess he was right about me needing that front brake 
My only experience with 5 speed hubs is with vintage Torpedo 5 speed hubs (both one and two wires) plus the older (two wires) 5 speed SA hub on my Brompton.
The hubs I am thinking about for you is some of the SA 5 speeds. Peopel use the narrow ones on bromptons but also on other vintage bikes. I suggest you look at what is available and decide if you want one or two sprockets (if you go for two you could later do someting similar to what cycle_maven suggested and get ten gears) and if you want a coaster (or drum) brake or if you want to avoid spreading the frame and use your Weinman (or other) brakes.

Is it a 36 hole rim you have on the bike now (and are you using that or a similar rim)?
