This I think is correct everything seems functioning correctly so far. Does this sound like the correct hook up ? Any issues ?
Any advice appreciated !

Sounds good. While it is generally not advisable to add new batteries to an existing older battery bank, nor it is best practice to combine 12v and 6v batteries in the same bank, you can do it. The life span of the new batteries probably will not be as great and the overall voltage you can charge your bank to may not be as high - depending in how good shape your 12v were in the first place. But combining the two 12v in series gives you one 12v to add to your 2 battery 12v bank and that is OK.
Since you already had the two 12v and you wanted to add battery capacity at the lowest cost, what you did is probably the lowest cost/best case in this instance.
I would buy a good hydrometer and routinely check the two 12v batteries to make sure they are holding up.
