Inventory Space and Data transfer limitations

[MistakeNot]

A frequent reason invoked for feature not to be added is the size of our inventory. o I wanted to throw this idea in the wild:

Would giving some of our regular inventory space to our chocobo saddle bags be a solution?
What are the difficulties and downsides you'd see for that sort of compromise? What would make that kind of compromise more palatable?

The saddle bags probably do create less load on the servers than regular inventory, so it should be easier to add extra space to the saddle bags than to the inventory.

Downsides are:
1) Saddle bags can't be unlocked until level 30 - but at such low levels inventory overload is rarely a problem
2) Saddle bags cannot be accessed in all places
3) If you want to use any item in the saddlebag it first needs to be moved to the regular inventory which can be a bit of a hassle.
