Out of curiosity, what would the results have been if Anne Neville had been pregnant by her husband, Edward of Westminster, prince of Wales, at Tewkesbury and given birth to a son?
The Lancastrians will almost certainly accuse the Yorkists of murder, even if it was entirely natural (accusations of poisoning tended to accompany almost any marginally suspicious death in those days). On the other hand, after Tewkesbury, and especially if Fauconberg's Kentish rebellion is still crushed, the Lancastrians are pretty much a spent force.Either he gets away to France and is the Great White Hope of the Lancastrians or if the Yorkists grab him and his mother he sadly dies of some childhood disease or accident. Infant Mortality rates are high enough that its plausible and if Lancastrians suspect its murder but can't prove it the Yorkists won't care.
Remember infant mortality rates means there is no guarantee that he'll very live long but assuming he does either he gets away to France and is the Great White Hope of the Lancastrians or if the Yorkists grab him and his mother and he sadly dies of some childhood disease or accident. He's simply too dangerous to keep around for the Yorkists and Infant Mortality rates are high enough that its a plausible line to put out. Lancastrians will suspect its murder even if it is a natural death but with Edward IV on the throne they can't do much about it.
I realize it's a big if, but say he survives to adulthood, perhaps he's spirited away to France or Scotland - and is the one instead of Henry Tudor leading the Lancastrian army at a lookalike Bosworth.

Richard, Duke of Gloucester would have killed the little Prince if it ever came under Yorkist power, we remember that Richard killed (ether by his own hand, or over saw the murder) of King Henry VI in the Tower of London after the Lancaster restoration (likely while Henry VI was at prayer) Richard also killed his own brother George the Duke of Clarence (maybe by drowning in wine) Richard would of course latter have King Edward VI and Richard Duke of York murdered in the tower
Richard was the hatchet man of the house of York and would do anything at all to protect what he viewed as the interests of his House, so if Anne Neville and her baby fell under the power of the Yorks, Richard would have done away with them (at lest the Prince)
Shakespeare much?
There's no more proof that Richard was any more responsible for those deaths (the princes in the Tower) than anyone else who stood to benefit from them: Margaret Beaufort, Lord Buckingham.
As to Henry VI and Clarence, Edward IV would've benefited as much from the former as Richard would've from the latter. And Clarence liked to think he was craftier than his enemies at court, and did nothing more than set himself up for his own death.
