Sounds like an interesting experiment. My batch of joam(though a little sweet) was very good, and so easy to make. It's got me hooked. I have an assortment of melomels, methaglins, three traditionals and a pyment. I also have a few 'cross breeds' between the types, including a cherry chipotle that's looking gorgeous. Have fun with your experiments and your very fortunate to have honey at that price.
I will say, regarding yeasts, I'm not happy with how bland ec1118 leaves a finished product. 1116 will do the job just as well and leave a much more flavourful end product.
