Making DIPA/ high ABV beer more palatable

Hello all- I got the Costco Stone sampler pack of IPAs and it IS good, but I can't drink more than 2 (7.5+% alcohol) and I'm starting to get tired of the same taste- I need variety! Would I create a good beer by mixing half of a DIPA with a Guinness? A half mix with non-alcoholic beer? Anyone ever done this before?

Thanks in advance!
