Only fill the tank half full, use duck tape or a compressing strap, and it would be under my magnetic tank bag to keep a little pressure on it. I could manage quite a while on that. Will just have to avoid going off-road for a while until I get a replacement shipped.
Though I think prying upwards on the cap might cause the lock to damage the tank, so that a replacement cap/lock wouldn't be useful at all.

The RX3 does not have an EVAP pressure sensor on the gas tank, so no DTC's that will illuminate the check engine light will be thrown.
To deal with your immediate issue, removal of the gas cap, I would take a Dremel cut off tool with a small diameter abrasive cut off disc and sever the cap at the hinge. This will allow you to open the tank to add fuel, although the seal will be sub-optimal, to say the least, when you try to close it. I would only put in 3/4 of a tank, at most, until a new gas cap assembly can be installed.
I agree with your assessment regarding prying up on the cap. You will definitely damage the lip of the tank where the latch engages with it, and you may not be able to get a reliable seal with a new cap afterwards. This would necessitate a new gas tank, which is more than a new cap.
In short, my advice is to destroy the cap, in the manner recommended above, and save the tank.
