Wish there was an easy answer to give, but I'm afraid it's about as good a question as 'how long is a piece of string?'. If you really, really want to do it, AND can afford to give up 2 years of your life to complete the training, AND have at least £50K available for the costs plus living expenses, then what's the harm.
You're well located in Northants for many different airports in East Anglia, the Midlands and perhaps the Thames Valley, and I'm sure there are guys who have been in your position and made a go of it. Times are pretty hard for recruitment just now, even for very experienced pilots (I'm not one if you were wondering, just got a first foot on the ladder so to speak), but you never know when Lady Luck might come knocking on the door. If you're genuinely prepared to give anything a go commercially, and prepared to be flexible with regard to locations and conditions etc, then have a crack.

Say hi to Scaldwell for me if you're ever passing, WD.
