You would have to mount an alternative pump.
I disagree to a point. He'* talking about using the bags for controlling ride height. Same function as ELC. ELC can raise the rear of the vehicle significantly. Anyone seen an ELC jacked SSEi at the track? Mine looks funny and aggressive at the same time. The ELC pump is actually quite capable. Especially on something like struts or airbags that have relatively low volume. Mine puts out 70psi at sufficient volumes to work quite well.
The disadvantage to air pads in the rear springs is that the springs are actually INBOARD. This makes them less-responsive to handling improvements as ELC struts would be.
In a nutshell, it would be cheaper and easier (as well as better for most purposes) to simply replace the ELC struts with new units.
