Size doesn't matter!
Believe me in 36 months time when you have unfrozen you're ATPL, have no bond, Proved to your employer you are good at your job and loved every minute of flying. You get that green license in your hand and have the hope that you're next LPC/OPC you could be doing it from the left hand seat, you will look back at that day in the hangar and say it was the right decision to stay where you are.
You don't have another job, a big shiny jet to fly or the money to pay for a type rating on a 737 ( not that there are any jobs anyway )
You, at this time are in the best postion you could ever believe you could be in. Don't waste it, or think what if.. Trust me, the greener grass you're looking up at isn't greener and at the moment isn't even there!
Well done for getting that job, just make the most it!
Oh and if you had a real passion for flying, it wouldn't matter what plane it was, just the fact it can fly would be enough to satisfy your desire to be in the sky!!!
