Yes it will work fine, as long as You don't exceed the switch maximum power rating (Voltage x amps), any 12v switch will work for this purpose.
Here is another source that also sells the custom actuator covers:

I was thinking a Layout #3 with an UP arrow symbol and FWD in line #1 for the Top and a DOWN arrow symbol and REV in line #4 for the bottom.
There are lots of places that sell those type of switches, just make sure it has the 2 poles and independent lights so it will be easier to use 12v for the lights and 48V for the FNR
