1. If we change brands, can we continue to use the hydraulic drive?

Well, It depends.... on just how your Hydraulic Drive system is designed.

If has a Motor that runs all the time (Like in anything over 100 Tons)
and you just use a set of Vickers Solenoids (Hough Marine type system)
to route your fluid for Port/Starboard movement, then YES, just about
anyones AutoPilot can besetup to drive your steering system.

If your system has a Motor that actually reverses direction to move the
Rams for Port/Starboard movement, then MAYBE you can retrofit a
"Glue System" to interface between any New AutoPilot, and your steering
system.

Best you go find a "Good" Autopilot Installer, or "Qualified" Marine
Electronic Tech and have him evaluate your Steering System for
convertability to some as yet to be determined AutoPilot System.
