Need help with parts for this switch

My trailer came with the switches in the first picture, a duplex with 2 single pole single throw switches and a 1 single pole double throw switch.

I removed these switches and relocated to the TV cabinet to make room for the added dresser.

I want to make a single switch plate and found the switch pictured in the 3rd pic. It has 3 ST/SP switches. I need a SP/DT momentary switch to sap out. Or a 3 switch wall plate to replace all the switches.

Would this wall plate work? it should be easy to find or call HL service.

Kind of "fugly" Alan
