Welcome to the forum , lesliesandler .
As others here , I have spent some time hunched over drafting tables , in my younger days .
You pose an good question , but I'm unclear as to how you'd use such a desk ... if you're planning on sitting @ it or standing while working .
The higher the desk surface , the tippier it would become ...
Rows of the great big herkin' ones , in offices flooded with fluro lights , were often leaned against by some pretty lge fellows , all without tippin' over .
I'd want to keep an eye on folks millin' around such a set-up as you're planning , so as to avoid hurt toes & feelings .
Perhaps a way around the tipping challenge would be to attach your pending pedastal desk to the floor .
If you're thinkin' of a portable/storable unit , scratch that last suggestion ...
I'd guess that the bottom line would be : how large of a surface area do you require for your work ?
If your work is not too large , there are certainly items like this around (as talesofthesevenseas illustrated) to be found & purchased by savvy 'tique hunters !.
