There is a problem, though.

Not all ships have the same emergency components and not all emergency components have the same ability amounts.
Even ships of the same design may have different emergency components intact.

And even if they do have equivalent strength components, the side effects of destructively using said components are not known.
EG:
Engines with EP ability. Using the engine gives you a 1-turn speed boost at the expense of slower travel until it is repaired.

Except in a fleet of ONE SHIP, trying to apply the "use component" order to a whole fleet is just asking for trouble.
