ADT Simon XT replacement

Hi all. I’ve got a Simon XT security panel from ADT with its associated wireless (non-z wave) sensors. I know these sensors won’t work with SmartThings, and I know that the Simon XT is a closed system and won’t work with any of our third party integration boards. Is there anything I can replace the Simon XT with that will let me bridge these devices to SmartThings, or am I better off not bothering and just replacing them? I like the more reliable security aspects of these wireless sensors, but I don’t necessarily want to have multiple door contact sensors on all of my doors.
