I also find the driver's footwell warm (although not extreme) and wish at times for the old style floor vents on the kick panels, which went the way of the dodo bird with a/c. Unless the hole is particularly big I doubt that's the problem, unless you just started to notice it with the wire installation.

In hot weather I usually keep the blower on floor and the speed one up from slow when driving with a/c off.

There is always the possibility that your catalytic is running hotter than normal.
