[R] Again on overlaying plots (a plot region within a plot region)

Dear R-users,
after seeking for help in R-search
I did not find any hint on my particular problem.
Countless help on "true" overlay, but nothing on this.
Please consider the following:
par(mfrow = c(2, 1))
T <- seq(0, 20, by = 0.01)
## PLOT 1
plot(T, 30*exp(-0.65*T),
type = "l"
)
points(T, 30*exp(-0.26 * T), type = "l", lty = "F8")
points(T, 30*exp(-0.15 * T), type = "l", lty = "39")
## PLOT 2
plot(T, 30*exp(-0.65*T),
type = "l",
log= "y"
)
points(T, 30*exp(-0.26 * T), type = "l", lty = "F8")
points(T, 30*exp(-0.15 * T), type = "l", lty = "39")
What I would like to do is to draw a square plot of PLOT 1 and
then overlay the *entire* PLOT 2 on the upper right corner of PLOT 1,
when there's a lot of empty space
I have to do that because the publisher asked me not to waste
much space with figures.
I studied for some time the Paul Murrell's excellent book "R Graphics",
but I did not find what I'm looking for.
As far as I understand, layout() is intended to flexibly
divide the plot region, not to subdivide the plot region
nor the figure region.
One solution could be to export PLOT 1 , say as png,
and then overlay on it PLOT 2 with pixmap() as in this example
http://www.stat.auckland.ac.nz/~paul/RGraphics/custombase-pixmap.R
but it seems to me a bit too much complicate
Thanks in advance for your time
