About Ankylomoloch

So Ankylomoloch is made from bumpy a small and asymmetrical Ankylosaurus and Stygimoloch a small dinosaur I was thinking should they resize Ankylomoloch and make one of the horns bigger? Now this is were the problem start as it made from a normal Stygimoloch that isn’t asymmetrical so the horn seems ok then it come to the size as bumpy is small and stygi is small so should they should resize it to be bumpy size and hnot change the horn size
