Ridge tile alternative

[Eddm87]

Leila be slaying my roof in a few weeks time, it’s a new section attached to the old, about two thirds up from the hip in the picture, new ridge comes out at 90 degrees.
the slates are 10 x20” and I can pick up from a reclamation yard.
The ridge tiles though are old concrete ones which are hard to get hold of and break easily.
I want to use a different type but one that doesn’t look too odd, wondered what people’s thoughts were?
It will be difficult to pull all the ridge tiles up and put new down and wouldn’t really be worth is as the Attached neighbours is identical to ours anyway.

thanks
Edd
