I'm with everybody else on the location of the softener. Besides it looks like you have a sump pump or something in front of the water heater. Marks approach is easier to do. If you can get a Sharkbite on the pipe out of the meter, switch to Pex, go to the softener and come back to the pipe in the floor. Put you bypass and isolation valves at the softener or any where along the way. That way your only real plumbing is getting a Sharkbite on the pipe out of the meter and one on the pipe going into the floor.
If you drawing is anywhere near scale, you have more room between the door and the water meter than you do in front of the water heater.
