warning old guy opinion...
Ok not so old 41... vanity dang.
I work with lots of students I have seen tons of piercing modifications and lots of gone wrong events too. I'd say wait, if you have something go wrong Costa Rica, you might end up in a private hospital, and that means your insurance may or may not cover the expenses of that.
Of all the piercings I have seen more odd issues arise from the tongue, lots of lisps, sometimes they go away sometimes not and even sometimes not after the removal is well healed. The septum doesn't bug me and if you chose to take it out at some point it heals up cleanly.
Just an old (er) guys musings you asked for an opinion and this is mine, no offence to anyone intended.
