wow it's so brilliant that they are willing to allow this... And if your son wants the acceleration too then I would say go for it!

It's great that they are willing to work with you and him on this. (may I ask where you are from?) we are about to start advocating for a jump now mid-year to grade 0 and then next year to grade 1, but even though it's a gifted school I doubt we will come right thanks to education department etc.

Bit of envy and happiness for your son all rolled into one here
