Wow, do click support that configuration? pretty outstanding I thinks, if it works and looks good then a real winner for that situation I`m thinking.
Yes, they do whats called mini-grid which works just as interchangeable switch units on the back of the plate (no yoke as with 'proper' grid)
You can either buy a 6 gang plate and the mix of 2ways and intermediates you need, or get a 6 gang switch and 2 intermediates to swap out the middle modules for, depending on whatever works cheapest
