Airlayer or graft old scots pine

[leatherback]

I have been working on this old scots pine over the weekend. In its future is a top-chop forseen. But, as it has such great bark, I am considering keeping the top on its own. So.. Now the challenge.. How do I get roots.

Anybody here any experience with grafting seedlings on Scots pine, or with airlayering? The latter seems to be a very long process?

I am thinking about getting roots in the bottom-left bend of the big trunk. The small trunk is the final tree.

I have never heard of anybody successfully air layering a Scots pine.
Lovely bark on that tree.
