If you already have a BA in ID you should be ready to rock there. I might get some flak for this, but the only reason to continue on to a masters in ID is if you want to teach full time in ID. And even then you can still teach full time in ID with a masters in Trans.
I’d focus on the trans schools, you still have your back up undergraduate in ID if upon graduation trans is tight. There are a lot less jobs in that feild, but if you pass and go for a masters in ID you petty much nullify your chances of getting a trans job.
Just my take, I should have followed my own advice.
