Ginger beer cordial

[Wrighty69]

I've made a gallon of ginger beer using a recipe online of 150g grated ginger, 10oz sugar, lemon and lime and general yeast. It's nearly fermented but very dry and watery. If I add Belvoir ginger cordial to give it a bit more body and taste will I still be able to prime the bottles with the extra fermentables?
Thanks
