Socially distant version of Handshake for Scotland

A handshake used to mean so many things from:

hello
to breaking the ice when meeting someone
to you can trust me
or signalling agreement

A new socially distant version of the handshake for Scotland would help with the easing of Lockdown restrictions and could mean specific things to make things easier for everyone.

In these times a socially distanced version of the handshake for Scotland would be useful to show people:

They understand what is required of them, regarding social distancing when they meet.
It shows the emotion of: it's good to see you again, how are you?
It would be signal Welcome in a hospitable (but cautious way)
When visitors to Scotland are allowed again, it could be publicised for visitors to know what is required of them and what it means.

It is inclusive - we would all be in the next stage of releasing lockdown together
