I don't think you are going to find a 'recipe' tat has those 2 kits in it.
ou are entering uncharted territory and that's part of the great attraction of home brewing for
those game enough to go there. Your could discover the holy grail, or just make something great
to drink.
As long as you stick to good quality ingredients, malts, hops and yeast, you shouldn't get something
totally undrinkable, though I got close once with an attempt at a Bock.
I'd be adding at least 500g of dry malt, maybe even a full can of liquid extract; and
keep the boil down to 15 min max, you already have plenty of bitterness in those 2 cans.
Whatever you decide, you're on the way to a fairly decent beer.
