Sure.
I forgot to mention that this parallelism definitely manifested itself *after* Sinclair left, after the Sheridan character was introduced. When JMS said that the story of Babylon 5 was very much Sinclair's story, it was still very early on in the series and he may still have been in the early stages of toying with the idea of a Sheridan-character. But we don't know that.
But the parallelism definitely only comes if you deal with Sheridan after Sinclair. Which makes your point equally as valid.
