Anything that says switch has definite switch positions that click, and those rotary switches need a reasonable effort to turn. You also need to work put how many poles you need to duplicate a 5-way blade switch, as each contact is independent, unlike a blade switch where positions 2 and 4 link two sets of terminals. I think a 5-position three pole rotary switch should suffice. More poles may be provided but you’d only need three of them.
I always view 5mm as sufficient thickness for the bottom of a control panel, so 1/4”, at 6mm, would be fine. So a standard blade switch can be fitted.
