can you use sierra uprights on a locost?

or must it be cortina to maintain correct geometry?

I know the haynes roadster uses sierra ones but the wishbones and mounting points are slightly different.

You can use Sierra uprights (many people have), but you need to make or buy suitable wishbones. The book wishbones are for the Cortina uprights and are not suitable for the Sierra.

Sierra Uprights have better geometry than Cortina also, so it's a plus. Although they can still be improved upon in a couple of ways...

It's best to build your own wishbones so you can control the amount of castor that you end up with (dependant on the main use of the car).

Just remember you will need to buy/make a mushroom insert for the top to replace the macpherson strut and allow the top ball joint to mount
