Advice on preparing wall

Hey, I have this small section of external wall (see attched image) that I'd like to tile over with more modern looking stone split face tiles.

I'm after some advice as to how best to prepare the area. I was originally thinking I would chisel off the existing stone but found the existing stone goes deeper than I thought. Therefore, I would need an electric breaker which I don't have. Now I wonder if it is possible to render over the existing stone then tile on the rendered surface.

What would be the best approach, hire a breaker and hammer of the existing stone or leave it and render and tile straight over, or something else I haven't thought of.

Thanks in advance

nice one, thanks for the advice.

I may now just render finish it the same as the rest of the house. This may be a question for the rendering forum but do you know if I can level this with a sand and cement based mix before rendering with weber monocouche? I assume I would need to prime the stone surface.
you could , but i’d use weber base coat.
call weber technical help they may suggest meshing it also and will be able to advise on priming.
i’d stick with sand cement personally , less faffing about and easier to prepare.
