Let's run with that idea for a minute. Seido has a 1600mAh battery for sale. Let's assume that's the highest capacity battery you can get and not change the form factor. That's only a 14% increase in capacity. Let's also say that the rumors were true and the TB was draining a battery in 3 hours. With the increase in battery size, that would give you a whopping 25 extra minutes of usage over a 1400mAh battery. 3.5 hours is still not acceptable and when factoring in with the cost of a recall .... it just seems very unlikely.
