I find the keyboard layout switching really awkward but for different reasons. On MacOS/Linux, setting the keyboard layout is global - under windows it's per-application and the default is for shift-backtick to switch between layouts which is something I manage to hit pretty frequently. When I was working on a host where I needed two layouts (US-Dvorak + US-Qwerty for other users) I ended up solving the problem using AutoHotKey to hook all keys and send a different keyevent. It was pretty gross but it bypassed all the issues I was having in a convenient way. Perhaps you could hook US symbols such as "$" and rebind to UK equivalents with AHK? Alternatively, creating a modified EN-US keyboard layout which has relevant key-symbols would also work / be less hacky, but probably require more effort.
