As Colin said, SGP will happily meridian flip and plate solve an EQ6 or HEQ5 with reasonable reliability. If it fails to reacqure and track well then you're no worse off for data. If it does then you may get hours more data - albeit with a sub or two lost when the RA re-establishes reliable meshing.
The higher the quality of the mount and tracking the greater the reliability. More recent belt driven mounts with low backlash probably fine.
