Nothing is impossible but you will be behind the drag curve re employability. Where are you intending to look for work? That will make a difference.
I am 57 and have been in the industry since my 20s. Happily I am very well established and my next move is retirement. With age comes a perspective and wisdom that the youth are yet to learn. So you'll bring something to the table, if not hours.
Depending on where you're aiming at the age thing won't be an issue. For most mainstream airlines, it might be - but who knows? Female pilots are still very rare.
