Sort of, just not simultaneously. HDMI always takes precedence. If the 360 senses an active HDMI connection, it will not output anything on component, composite, vga, S-Video, etc. If the 360 does not sense an active HDMI connection, then it reads the 3 jumper settings inside the cable's connector housing to determine what type of cable it is and then outputs that video type. So, if you have a standard component HD/SD cable, you can output component in HD or SD (composite in SD only), depending on the switch position, whenever the HDMI connection is not active. That is, the TV to which the HDMI cable is connected, is not powered on, or is switched to a different input in some cases.
Of course, using a component cable like that, will induce the dreaded HDMI switching reboot issue, where if you temporarily switch your TV to a different input than the 360 HDMI connection and then switch back to it, the 360 will reboot itself. If that doesn't matter to you, then by all means, go ahead with your plan. If that does matter, then you're out of luck, as there is no way to prevent the HDMI reboot issue while still retaining the ability to output component, composite, vga or S-Video without swapping cables.
