Your comment on the gogos got me looking a little closer at the Echos. Have a couple of retired Echo-E cartos and screwed an old battery on and wiggled it back a forth until it came loose and pulled out of the shell. Appears the only difference between them and the 901 threaded units is the working parts are just pushed in further. Will try to figure out what I can thread to the 901 connection that will give me some leverage to be able to pull one of them apart.
The first step will probably be to place the carto on a firm wood surface, use a small socket just smaller than the shell and tap the working parts in further with a hammer to break the seal then pull it out with some threaded device. If I have any success I'll post the results.

Unfortunately my efforts were a total failure. On the Echo-E the slotted ring on the battery end is glued in and easily removed. Had hoped the slotted vent ring on the regular Echo was separate, not so. When I tapped the working parts further into the shell I found the vent ring was part of it and a little larger than the tube. The consequence was that it wedged in the shell with no reasonable way of getting it out.
My next effort will be to cut the shell 3/16" in from the threaded end to get things out, cleaned and re-inserted into a somewhat shorter Echo shell.
FWIW the DC Echo I'm working on has been about 15% of my vaping for the past three months @ 4.6 to 5v and is still working reasonably well. I'm curious as to whether or not a cleaning and dry burn will bring it back to something closer to it's original vape and flavor as some have done with the SC Echos. Inquiring minds want to know.
