Just to update the thread:
I never actually got around to fitting a new hanger, but I never had any issues either. I suppose that could be because the hanger is unnecessary, but it could also be because I have only put 8 or 9k on the car since I've owned it. Take that for what it's worth I guess.

So I figure it all comes out in the wash. I've yet to see issues with it and among some very well respected aftermarket manufacturers (M2, Pettit, Mindtrain, etc) nobody found it necessary to include the support.
IMHO, the bigger concern is leaking at the 2-bolt flange. It's most prone to leaking when flexed up-down, and a bracket would help that a lot. I really don't get why manufacturers use those 2-bolt designs, they suck.
If you have fab skills and material to make a bracket, I say go for it. It can only help. I don't have that stuff and I don't feel it's critical that I go to extra effort to get one made.

Thanks for the update.
You're right it's probably not 100 % necessary, but I'm a little OC and thats what stopped the worrying.
Those 2 bolt flanges have annoyed me since my first FC. I guess they make manufacturing and assembly easier, but they are a service nightmare and I swear I spent as much time getting my DP to cat flange to seal as I did installing the engine.
On the other hand, the rest of the exhaust is on rubber hangers and the exhaust system itself (particularly thin-walled stainless downpipes) are much less rigid than the stock exhaust. Therefore it will apply less load on the downpipe connection than a stock downpipe with hanger removed.
