<p>Let's say I want to rewrite the software behind the hardware of current asics. Would it still mine, for example, sha1 algorithms orders of magnitude faster than a normal cpu would?</p>

What do you mean by "the software behind the hardware"? The hardware cannot be changed, it is designed specifically for SHA256

How easily can asics be ported over to other sha algorithms?
