is there a command to make a live version of arch with my configurations, from the current installation?

I don't think so, at least it's not built-in into pacman, if that's what you're asking about.
Particular answer is no.
There are downloads which package archlinux packages but then you can use a command to produce an installable "live" archlinux USB flash or cd/dvd rom.
CTKArchLive is one such download. It provides a configured archlinux openbox of 500mb.
You could arrange it after downloading to provide your desired config perhaps.
It isn't a case of direct to "live" from archlinux OS already installed.
