Ok so getting the busted ones out and the lead strip to hold the
replacement in/up fixed is not not a problem. But how do you get the
top of the replacement slate onto the batten that nails of the next
row up go into? I've tried various juggling and twisting and lifting
the slates above with the ripper but with no joy.

Slide the slate rip in first over the top lath then slide the slate up
on top of the rip. When the tail of the replacement slate is level
with the other slates slide the rip out. Try a thinner slate if tight
or you can hit the top of the slate with a hammer to form a reverse
riven edge so you have a chamfer which will help ride over the lath.
