Possible... Yes. Practical... No. Unless you have money pouring out your ears and want a project, go for an SS and if you have money pouring out your ears go for a Z/28
As everyone said, factor in time, price of all parts necessary, etc... Cheaper to trade-in and grab an SS. Something also to mention, obviously is if warranty is important to you there will be none in an engine swapped Camaro, from GM at least. Though if you're modding its irrelevant but just something to think about.
