That basically describes the way you should probably wire things.

use the "stock" as an on/off switch for the aux lighting.  Then hide a
little double throw switch to switch between the fogs or driving lights.

these would switch low current, to control two separate high current
SPST relays that actually fire up your two sets of bulbs.

the high current relays would get their juice via a fused wire from the
alt output, battery + terminal, or jumper terminal.

The switch and relay control setup would also be wired to limit aux lamp
usage to appropriate conditions, ie, only when low beams are on (using
switched low beam power to trigger the relays would have this effect).

Of course, if you actually want to see at night you should save the
effort & $$ and invest it in euro lights for your car...
