Developing A Scenario

THREE years ago I paid £2.99 for a "Western Rider Cowboy & Indian Playset" in a gift shop in Paignton, Devon (https://timspanton.blogspot.com/2017/10/cowboys-indians.html).
The following year I paid about £7.50 for a "Wild West Playset - Cowboys & Indians" in a toy store in Olomouc, Czech Republic (https://timspanton.blogspot.com/2018/08/toy-lightning-strikes-twice.html).
Both were fun purchases, but I found no way to turn either into a wargame.
However, with time on my hand - haven't most of us, right now? - and a renewed interest in Bob Cordery's Portable Wargame series of books, I decided to take another look.
One of the things inspiring me was realising I would not need to buy a new gaming cloth - I cannot recall how much my green gaming cloth cost, but I know it was not cheap.
I guess I could use the green cloth for a cowboys & Indians game, perhaps set Last Of The Mohicans-style in in the eastern United States. But in that case the palefaces would not really be cowboys.
Instead I am using a sand-coloured fitted sheet which easily fits over one of my approx 6ft by 2ft 6in gaming tables. I suspect it would also fit over both tables side-by-side.

Since I am adapting Portable Wargame rules, the next step is to create a grid, which I do with green beads bought from a pound store for exactly this purpose.

So far, so good. But I hit a problem when I came to remind myself of the contents of the two playsets. Unfortunately, the figure scales are not compatible.

Colourful contents ... but not matching

Never mind - this is a toy-soldier project, not a modelling diorama.
I will concentrate on using the smaller figures, which go perfectly well with the scenic features, and the smaller of the two wagons.
Indeed the only figures I will use from the larger-scale set will be the two mounted cowboys and the two mounted Indians. I need to use them as the smaller set has no men on horseback.
