Aircraft was backed into the hangar for a L/H MLG strut repack; and the Aircraft X's jacking had began. Halfway through the shift; Aircraft Y had an [priority] landing with an engine issue. Local management wanted Aircraft X towed out; Aircraft Y towed in first; then Aircraft X back in. [The following day]; Aircraft Y was ready to come out of the hangar; but it was trapped because Aircraft X's L/H MLG lower leg was removed.Management elected to direct the winglet to be removed from Aircraft Y; fill the wing with fuel; to make it heavier; and Aircraft Y was towed out; wing under Aircraft X wing; with 3 inch space between wing surfaces. If Aircraft Y would of shifted; and wing raising up; it could of caused Aircraft X to be knocked off jacks; and jacks puncturing wing fuel tanks; possible fire; personnel being hurt or even killed.If this would have happened; local management wouldn't have taken responsibility!Poor decision by Management. When a lower leg is removed from a strut; you take a chance of having corrosion issues. Why would an aircraft with an engine change be placed in the hangar before a strut repack?This violates every practice we've been preached. Never; never jeopardize damage to personnel or equipment.
