What does the AMM say about removing the actuators? I'm sure it says to jack the a/c clear of the ground. I would never do otherwise.
If there is a special jig, or special piece of ground equipment you can install in place, then, may be...
Actuators are also used as drag braces or side braces, and are "locked" by hydraulic pressure;that's what prevents the gears from folding under any condition... there is a chapter on ground equip. and such.
