I guess that could work but I wouldn’t really like relying on Stone Curse because of it’s ridiculously long CD of 82 seconds. That’s the only reason I thought you might want more CC but Pyro damage is very nice to have 
I mean if you’re only using Stone Curse for charging Meteor only, you’re set but if there are any other charging skills (not sure if you can interrupt Electrocute and Hail charge or not) that you want to cast together with Meteor, there might be an issue. Also you’d be limited to CC of 8 enemies in front of you which is a lot but if there are more aggressive mobs behind you, you’ll still probably have to run or something. I’m not sure
go test it out and prove me wrong since I think I’m just bias against Elementalist without more CC.
