Well as a oldish starter myself now 40 flying a turboprop for the last 2 years I would say...... it's just down to market forces really, the good ol supply and demand, it's amazing how the airlines "criteria" of age experience etc... dwindles rapidly along with the supply of pilots.
If you want to do it then why not..... but be aware of the number of f/atpl's floating around you in the sea of no jobs.
I'm sure this will change but when?... can you really put yourself through the heartache, frustration and financial suicide, to be just another f/atpl??
I'm not wishing to pour scorn on your chances but give a realistic angle on the current situation.
Good luck.
