I can understand the desire to put a tank on a reo. I often screw un-reo-nish vaping stuff on them, if only to quickly check a flavor or device. Adapters aren't really bad as long as you just measure them before use. Everyone should have a multimeter anyway, so you can:
0) Screw Atomizer on adapter - check that the adapter center pole isn't protruding too far, if it is, don't use this adapter on anything, send it back to the vendor.
1) Remove battery
2) screw in adapter with atomizer (or tank, ...), don't overtighten
3) measure atomizer
4) insert battery
5) profit
To measure the adapter with the tank or atty, put your multimeter to show Ohms, put one lead to the spring screw or spring itself, put the other lead to the metal strip that is normally touching the battery plus terminal. The multimeter should now show sensible resistance (1,5 to 3 Ohms). If the adapter is shorted you will get < 1.5 Ohms, most likely around 0.5 Ohms.
I got used to the adapters I have and I am confident they won't short anything, I don't need to measure them everytime I use them. These work well so far:
