Possible to cut Heat Shrink tubing lengthwise and reattach?
Actually it is possible. I did it myself.


  1) You have to cut the shrink tube lengthwise.
  
  2) Wrap it around the part where you want to apply.
  
  3) Apply superglue to the separated part and reattach them (it is
  not necessary to attach the ends exactly at cut part, you can attach
  them as you desire).
  
  4) Apply Heat and VOILA it works.


Please do some experiment before you commence this procedure.

P.S - I know I am 4 years late. Just wanted to share.
