Modification Planning - Suggestions Please?

Ok, well that donor loco turned up (it's an E2 class 0-6-0 tank loco) and I've decided that I will instead of converting it will take UCEWPN's suggestion of renovation instead

My reasoning being;

• It's in way better condition than the original listing showed, sure its missing a smoke box door and its dusty, but apart from that its pretty much complete.
  
• It runs beautifully, a bit of oil and a service to remove any fluff/debris and it will be a great little loco
  
• I don't actually have one of these class of loco's and its a lovely looking livery!
  

Anyway, to illustrate what I mean here's a couple of pics of her;
