No, there's currently no way to control HDClone by command line, but we are working on implementing such a feature in one of the next major releases.
The problem is that it has to work both on the self-booting and the windows version, which makes this task a bit difficult.
As for the speed reduction: there's one point in the extended options called 'USB Cooldown', which doesn't limit itself to USB drives but makes a short pause after each block read, which could be what you're looking for. There's currently no other way for artificially slowing down the copying process.
