Define "more efficient"? You would need to build new storage system for the lifting gas and add a lot of systems to manage it. On the other end you can just make the existing tanks slightly bigger and put a bit more fuel in them...

It would not help much (going up is only about 15% of the effort of going to orbit, the rest is sideway acceleration) and it would add a lot of complexity and cost.
