The most important thing is to be happy, so if you want to fly for a living, best just do it. As far as I am aware, you will still be in the age bracket for turbo prop airlines. They prefer more mature people as there is less chance of them bogging off to a jet airline as soon as they get the experience! Commercial instruction is another good career path.
The benefit you have over the 21 year old daddy funded/massive loan guy out of an intergrated course is that you have other skills to fall back on if you can't get a flying job straight away.
