Dilemma Where shall I base my shoebox layouts on?

[Oldman]

 
Do I try and model a specific area or use modellers licence -with it looks ok as the area.
Current loco  stock is as follows:all loco's were still running in1962 apart from my Union Mills 3F  out of service in 1957. (all are in BR Black)

3F  (Union Mills)was based at Cricklewood East
2F  (Minitrix)  was based at Birkenhead
M7 (Dapol)   was based at Yeovil Town
94XX (farish) was based at Bromsgrove

Coach Stock is currently
Dapol  Autocoach in GWR brown and cream.
2 off Farish Mk1 stock in Southern Green.
2 off Slam door non corridor stock repainted in SR green.

4 wheel LBSCR coaches as on IOW to go with my Terrier.

Goods Wagons.
All  assorted 10' wagons plus Brake vans from LMS, NER and SR

  Bear in mind what I already have coach wise was purchased for my Lyne End Layout

If its in a shoebox then presumably the Plimsoll line and perhaps Sandalwood station   

and don't forget the pump house, the duke of wellington pub !

(and yes my old Welsh port layout was called Doc Marten)

What about starting when your stock was first introduced then do a timeshift as the years have gone by till they stopped using them?

With a mix like that, how about a Heritage line?, you can run whatever you fancy. With Holiday monday coming up it will cost you a fortune in people . Cheers john.
