That is certainly a way to go about it. Have you tried using the Med Pack temporary power from the S.T.A.R.T. vendor? It's 25% of Base Health, recharges every 60 seconds, and you can purchase 100 uses at a time (500,000 inf per 10 charges). Of course, temporary powers may not be suitable in all situations, so having a pocket heal just might be the right answer.
