Thanks all for the suggestions, just to reiterate, £1500 was an absolute max, I'll consider anything up to that amount. 
 
Missed out on the marcus miller jazz. After a bit more research I stumbled upon the Modern Player Jazz series, seems like a viable option, skinny neck, will provide a different sound to the P (and thick and heavy due to humbuckers!), passive (forgot to mention I prefer passive, my pedals provide quite a high output with a lovely deep sound so active pups would be a bit too much).  
 
Any thoughts on this series? 
 
Or other suggestions, keep them coming!
