it'd be better if you left the saddle off

Don, does this not cause the post to slip inadvertently when you don't wish it to happen. Is there not something missing from the pack?
If you weld on a schraeder valve to your seat tube, grease post and insert as explained and then presurise your seat tube I reckon you might just be on to something. Make sure the inside of the seat tube is particularly clean first to avoid unnessary stiction.
