To the framebuilders out there... Some frame mods

Hello all.
Thought I'd ask on the forum before I turn to the bigger builders..
I have a very early (No. 9) John Spooner frame that's turned into my daily. Really enjoying it but was hoping for a few (small) improvements/changes to it. Hence my call out here to see if anyone in the UK would want to take this on..
So the mods I'd be looking at are:

• reaming of HT to allow a flush fit of the CK HS (1")
  
• BB shell reaming
  
• TT brake cable guides
  
• DT bottle bosses
  
• chainstay dimpling on the inside to allow for 28c tyres (25c fit fine)
  
• change of seatstay bridge and chainstay bridge to allow for a rear brake and mudguard
  
• mudguard mounts somewhere on the seatstays
  
  

Any thoughts and ideas all welcome. Painting it is not an issue. No rush either and many thanks. T
