Realistically, no. The Rising had practically no popular support, and as others pointed out was never really intended to succeed militarily. It has to be remembered that the vast majority of the Irish public at minimum acquiesced in, and often supported, the British war effort up to the Rising. For Ireland to become another front for the British, you would need one of two things:
1. A full-scale German invasion of the island. This is an impossibility without ASB changes - even if the German fleet had wiped out the Royal Navy, the Germans would hardly have had the capacity to land & keep supplied a major expeditionary force in Ireland. Moreover, if they ever did have the capacity in such a situation, why not just invade Britain directly?
2. Make the Irish Catholic population much more hostile to British rule. The only somewhat-plausible way this could happen is if the Home Rule crisis had exploded into open fighting in 1914, in which the British army sided with Ulster and fought the Irish Volunteers. Absent something like that, there is simply insufficient popular support for the Irish population to rise en masse against the British.
Oh, and I'm totally stealing 'Moron' Maxwell the next time I lecture on the Easter Rising!
