求助一个比较状语从句的省略语法点

在CR题目里看到一个选项看了八百遍看不懂，感觉是比较状语从句的省略，求大腿们指导！

A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.

would by是个什么结构。。。比的两方是primer和new的weight嘛，后面那个would by balabala修饰的是啥？谁又对capacity产生巨大影响晕。。。

是would weigh，省略了前面的verb，是很常见的结构。

飞机上的primer涂层的重量大于新型涂层的重量，而这一重量上的差距足以影响到飞机的载货能力.

would weigh是虚拟吗在这里？would byXXX是强调重量差异的程度嘛？would weigh的主语是不是还是句子主语primer layer？
非常感谢！！！

primer weighs more than new coating would weigh by how much? By an amount large enough to bla bla

would算不算虚拟我不知道，意思你明白了就好
