Short answer: no, probably not.
If you were using a prefix yourself, I believe Harmony can be instructed to treat that prefix as higher priority than others, which would let you get in before the method is detoured. But I assume that if the problem were prefixable you'd be doing that already.
I imagine you could somehow persuade Harmony to target a patch, but it would be very sensitive to load order (the patches are numbered but I don't think they're distinguished beyond that, so you'd have to rely on the other mod's patch being the first) and if you're going to be transpiling it, you'd need to study the other mod's code in enough detail that honestly, it'd probably be easier to just rewrite it for compatibility.
