Yes it is possible and it's for FREE.
Just go to a Globe Business Center and have your sim exchanged... in fact the most of the new LTE capable sims now are already triple cut (mini, micro and nano).
Yes, that's possible,. Visit any Nearest Globe store, if under your name just bring at least 1 valid id, Free sim replacement, same number and activation within 24 hours as i experienced with my nano sim. Else valid of both parties and authorization letter. blitzkrieg
