Not by default: invisible is in yank-excluded-properties, so the LRM
character will become visible after yanking.

Then don't make it invisible, it displays by default as a very thin
space character.  You can see that in action in the HELLO file, on the
Arabic and Hebrew lines.

No, and doing that is a very bad idea.  For starters, it means that if
you send such a copy/pasted text to someone else through email, they
will see the text differently than you did.  Using LRM is the only
idea that works well and without complications with plain text.
