Jim,
Except the ones that would have been forcibly conscripted to fight in W.W.1.

You are wrong again!
The conscription bill predated the rising.
There was never going to be conscription in Ireland, rising or no rising.

That did not stop 210 000 Irishmen joining the British Army in WW1.
By comaprison "the IRB (responsible for the rising)probably never exceeded 2,000 members"
