scaling a plot via imagesize

Hi,
for output purposes I'd like to control the size of the plotimage. This 
is no problem using ImageSize. In addition I want the whole plot 
including axeslabels, ticks and so on to upscale proportional to the 
imagesize. For example if I set ImageSize to 500 and the plot looks 
fine, I want that when setting it to 1000 all the fonts should be twice 
as high, the lines drawn should be twice as thick and so forth. But for 
exampe using the TicksStyle directive with a fixed number for the 
FontSize does not do this upscaling.
The solution I have right now is that I obtain the current ImageSize via 
AbsoluteOptions and then do the upscaling manually for each critical 
Option. Let's again take TicksStyle as an example. Let's say a setting 
of TicksStyle->11 looks fine for ImageSize->500. Let furthermore be 
imagesize the current imagesize. Then I would set 
TicksStyle->(11*imagesize/500). This solution works, but if the 
ImageSize is set to Automatic it fails, because AbsoluteOptions returns 
Automatic for ImageSize and not the actual value.
This is not a huge problem, because my current solution works, but I'd 
be glad to hear a more elegant way, if there is one. Perhaps this one 
involves less effort.

Thanks in advance.
