Like many others, I want to replace the gate valves on my washer

copper pipes where I have good access, which I do not have in this
case. *So what I'd like to do if possible is put a ball valve directly
on the outlet of each existing gate valve, and then attach my supply
hoses to the ball valve outlets respectively - all using threaded
components.

I realize this will involve a variety of adapters and fittings, if
it's even possible at all. *Can someone privy to plumbing terminology
help me come up with a bill of materials to hand to the local parts
counter? *Or are there compelling reasons not to do it this way?

Thanks!

A ball valve would accomplish what the OP wants to accomplish:

The ability to shut off the water after each use without messing with
the current gate valves, for fear of them leaking due to not being
used for many years.

I don't think that restricted flow is anything that the OP is
concerned with.
