不可以,因为weigh 是实义动词,实义动词作谓语的疑问句要借助助动词DO / DOES / DID ,因为主语是IT 是第三人称单数,故用DOES

换成is就要改为How much is it weighing/is his weight或者作系动词，或者用正在进行时。
原来那句How much does it weigh.是一般现在时

因为 weigh 是行为动词，没有系动词be，也没有助动词be

因为由how引导的一般疑问句，句子是一般现在时，句中已经有weight这个动词了，如果把does换成is，整个句子的时态都要改变了，所以这里只能是助动词

不可以，weigh（称重）是一般动词，不是be动词，必须借助助动词does构成疑问句，表示“这个东西有多重？”希望我能帮助你解疑释惑。
