I think you should be multiplying the diameters of the universes involved, and then extrapolating the requisite universe volumes from them. It's likely they actually will take it seriously in some way, considering how "intersected" the researcher team of Death Battle, i.e. the "G1s", are with VSBW's general "sphere". The general vs debating sphere seems to be in a very "hyper-permissive" era - 90% of which I attribute to the craziness of VSBW - where everyone is (at least) universal, everyone has infinite speed, nothing is an outlier or inconsistency anymore, and liberal scaling is the norm. But here's the thing though: different interpretations, "debunks of debunks", the growing number of relatively prominent "VS YouTubers" who think that comic book "high heralds" are universal minimum, etc. It would be arrogant and frankly delusional to think that you could singlehandedly curb any of that, especially on something with as much potential for subjectivity, as it does objectivity...
