Can I make custard-base in bulk and freeze in portions?

Hi all,

I was wondering if I can make multiple batches of custard base, and freeze them into individual portions. When I want to make ice cream, I thaw a portion in the fridge and then throw it in the machine when it's thawed. I know that the eggs are emulsified in the cream, so will it split when thawing in the fridge?

Thanks
