How often are you likely to remove the pan, noting the fact that it was there for 6yrs!Is the tension not an issue then? Would it not still be better to relieve it? And at least give me some movement in the toilet in the future without always having to replace the connector!
Ok ,if it's that much of a concern for you, by all means change the set up.

Where exactly is it leaking, is it at the pan connector where it connect to the pan spigot on the back of the toilet? If so use a back to the wall flexi connector, it has a full sized jubilee clip that hard fastens to the pan spigot.
Ah ok, is it a push fit 110mm socket that's in the floor or just a piece of pipe sticking up that the pan connector is pushed into?
Look at a spigot elbow (or m&f) ringseal.
Take the pipe out of the socket that's in the floor and push the spigot of the new elbow into it. You can get long spigot elbows and can cut the spigot length to suit.
Also, from photos, it looks like flexi is going uphill away from the pan. If this is the case, cut a bit more of an arc out of the decor panel behind the pan, so that there nothing obstructing route to floor outlet.
