First of all, it seems obvious that an MPL is too restricting.
You could very well find an instructing job, or a private jet company, but only with a normal license.
Then, two things to consider :
How much would it cost to finish training, from where you're at ? Forget about what is paid and non refundable, if it's lost it's lost. But if the school does not want to refund you a large sum, but would accept converting it to another form of training, the frozen atpl could be cheaper than polish modular.
Some years from now, when things will pick up (I sure hope they eventually will), will easyjet hire you if you went modular and did not train at the expected place ?
These are the two most important things to consider, amont what I see.
