There are some talents that are technically both NXT and WWE roster members;
Jinder Mahal, Drew Mcintyre, Trent Barretta, Usos, Tamina, camacho, cesaro has made several appearances on NXT lately too.
Personally, i wouldn't waste time on people over 40 being put in developmental, it's not a good investment of time. So people like Khali i'd forget it. I would have said Tensai with a revamped character (even if it's still Tensai gimmick) but i think he's a bit too old for a solid investment.
I'd say those who need character development/need to get used to their new character before being called up;
JTG (i have no idea what his gimmick is; he wears a black jacket, that's about it)
I'd say have Johnny curtis do a similar gimmick to guage a reaction before debuting as fandango
Usos (who currently have been relegated to NXT lately due to their feud with Ascension, mainly because we actually have a bit of depth to the tag division currently so NXT gives them something to do whilst not on the main shows)
Primo and Epico (They are hispanic and have a hot valet. That's about it. They are basically tag team division's version of heath slater - before 3mb)
However, i think anyon ei can think of that needs help are probably going to be released soon anyway. Plus, it takes time out of investing in other talents.
