Rurik, remember the Law of Equivalent Exchange. Your sword can be reshaped through alchemy, but it can't gain mass from it unless you have a source to work from. If it extends in length, it has to be reduced in other dimensions...I'm sure you can still make it work though. Just sort of kicking in a bit of setting flavor.
Here's my semifinal build (pending approval).

[sblock=Background]As a very recent recruit during the dark times that marked the ending of Fuhrer Bradley's regime, Gail is a valuable commodity in the new Amestrian military. Old enough to have some experience, but young enough to be free of the corruption that had crept into the military's career soldiers and commanders. Smart, coordinated, and with a natural gift for alchemy, she passed her State Alchemist exam just in time for a plum assignment.
In the interests of preparing for the cultural impact of free trade with Xing, and as a gesture of peace and goodwill, the new Fuhrer Mustang negotiated a limited 'exchange' program where a few Amestrian alchemists would go to Xing to both teach and learn, and a few Xinguese specialists in Alkehestry would come to Central to do the same. The program went well, and yielded at least one unexpected benefit.
Gail has returned just in time for her knowledge of Xing and the desert, which she's crossed twice now, to aid the investigation of the mysterious problems along the Xing trade route. So poor Gail was sent out again no sooner than she'd set foot on the cobbled streets of Central to report.[/sblock]
