LOL and I thought this thing was going between two highrise apartments across from each other on Fifth Ave in Manhattan!

You don't want the knot to go through the pulleys. If the knot goes through, your clothes will go next.
Sag will keep the ropes well apart. If you have 10 pounds of clothes 50 feet from the house and the sag is 5 feet, that will be 50 pounds on the line and 100 pounds on each pulley.
If the sag is 1 foot, that will be 250 pounds on the line and 500 pounds on each pulley.
If you can transplant the trees 10 feet from the bathroom window, that will mean less strain on the line and pulleys. If you can hook the house pulley to an interior wall, you can hang and remove the laundry standing inside the house... much faster and safer than leaning out a window!
It depends on how the rope is constructed, not on its use.
There are two joining splices for three strand twist rope: short and long.
The short splice increases the diameter of the rope(s) where they are joined. Here's a how to...

The long spice does not increase the diameter...

However, there is no reason to splice the rope, a knot will do. I know you are worried that the knot won't pass through he sheave but it doesn't have to...
You start hanging clothes with next to the knot. You pull the other side of the rope so the knot travels away from you and then hang more clothes. You repeat all this until the knot reaches the sheave farthest from you; when it does, you have hung all the wet laundry you can possibly hang, a splice won't let you hang more.
Hanging out a window to hang clothes from three stories up injects a certain amount of danger.
You are talking about a 100' long line. That is a L O N G clothsline, most would be in the 30' or less range. The longer the line the more sag there will be with a given weight. Now, if you hang up 100' of wet socks or underwear, that is one thing; 100' of wet towels and sheets is another.
Better check and see if you are legal. It says the right to keep and forearms shall not be infringed, but now days you might need a permit, especially if concealed hand arms.
Old folks tend to shrink, not stretch vertical. And stretch horizontal.
Steel wire will not last forever, even if coated. What would work would be coated stainless steel wire, such as they use for lifelines on a boat. But if you bought it thick enough for a clothespin to get a good bite, it would be too inflexible to run through a pulley, unless you had a really big pulley, and in any event, the cost would be extreme.
I think UV protected Dacron line, thick enough for a clothespin to grab, would be your best option in terms of weather resistance and cost, but even that would become stiff after years of exposure.
I used it to hang a bird feeder 12 or 14 years ago, and it still works, but is getting stiff and hard to run through my pulley.
I think you don't need four pulleys; two will do. Four would be needed if you were using metal wire, which doesn't like to be bent back upon itself, so you would need 4 90 degree bends.
With a more flexible line, you would create a loop, with a upper and lower line. Knot it securely in the upper line, and pull the lower line until the knot is near the far pulley, then start hanging whatever you are drying from the lower line. Hang one item, then pull the top line; the knot will move toward you, and the first item will move away. Then hang the second item and repeat the pulling. Eventually the lower line will be filled, or you will be out of items. Reverse to collect the dried items. The weight of the drying items on the bottom line will keep the lines apart. You still need some kind of device to allow stretch when the tree sways, but limits stretch when the line is loaded.
I say use a knot, because splicing requires skill and experience, and I wouldn't go through learning that procedure for a one-time job. Also, if well tied, a knot can be untied if you want to take the line inside for the winter. You can't do that with a splice.
Here's an example of a 125 foot long clothesline! :)

Actually, it's a cable we put up for a suspension bridge, but, it's at least 50 feet high at the downhill part and only about 15 feet high in the uphill part - but I figured it would serve by way of example that it can be done.
