Temporary brand repositioning (9)
I believe the answer is:
makeshift
'temporary' is the definition.
('makeshift' can be similar in meaning to 'temporary')
'brand repositioning' is the wordplay.
'brand' becomes 'make' ('make' can be a synonym of 'brand').
'repositioning' becomes 'shift'.
'make'+'shift'='MAKESHIFT'
(Other definitions for makeshift that I've seen before include "Cobbled together" , "What 11 [SEAMSTRESS] might do" , "temporary measure" , "stopgap" , "serving temporarily?" .)
