I agree that it's a complex situation, and that many different approaches will eventually need to be brought to bear. What concerns me about introducing a big lump of complexity here is disentangling the effects of each part and of their interaction terms. We're not, to put it mildly, set up to do ANOVA (https://en.wikipedia.org/wiki/Analysis_of_variance ) , ANCOVA ( https://en.wikipedia.org/wiki/Analysis_of_covariance ), etc. on changes. Given the above, I'd like to make the case for changing just this one thing at first and seeing whether the difference it makes is generally positive.
