Tiger's car is a post facelift model with improved boot hinges that open wider.
The facelift was around 98 / 99 but there was no distinct cut off point so every car is a bit different.
The boot lid is easily detached so if you go for your spare boot idea all you need to do is find one with the same fixing points, there were at least three variations of hinge arrangements that I know about so it would be a matter of physically checking interchangeability.
