Theres no command line option to do that.
Normally in windows we'd use something like AutoIt or AHK to pull it off, but Chromes a special case.
Chrome doesnt work like normal apps, for instance if you have a theme on it draws those things itself so the normal AutoIt/AHK/Windows ways dont work.
If you turn off themes then windows does draw those things, but Chrome doesnt play nice if you turn them off.
You can use this tool to play with windows....
Try clicking on Chrome going to the styles panel and turn off WS_SYSMENU....now trying resizing Chrome...it dont like it.
The closest I got was to first turn on WS_CHILD and then turn of the above. Now you can resize but theres other little probs and god knows what else doing that will do.
So, sorry, it may be possible, but I dont know how ;)
