Interesting Question. However, The Doctor wouldn't get 10 more regenerations. 1: River regenerated only twice, so if anything the Doctor would get 11 more Regenerations. And 2: River gave the Doctor all her Regeneration energy to cure him from the poison of the Judist tree. She used up the remaining 11 lifetimes to cure the Doctor. And finally 3: A Time Lords Regeration is restricted only by the Eye of Harmony, an artificial black hole created by the Time Lords. When they all died in the Time War, the Doctor escaped with it in the heart of the TARDIS. Now that he controls it, he can have infinite Regenerations. However, the Judist tree disabled his regenerative ability which is why he needed River's energy. I know this seems long-winded, but it's the facts.
