I have a 5 element 6m beam yagi. If I find the correct diameter aluminium tubes to extend the elements to be a 10m beam; is that doable?

The beam has a gamma-match. Would I have to get longer parts for that as well?

You need to almost double EVERY physical dimension, including length of the boom and spacing between the five elements. FYI, that will more than double the windload, so you may also want to stiffen the support structure.
