I am wondering what folks think about converting a LW storm in .270 Win to .280ai?

I'm in the market for a .280ai, but I also want a lightweight stainless rifle. The Ultralight is more than I want to spend. Seems like you could pull a stainless barrel off a .280ai Storm or AxisII and replace the lightweight 20" .270 barrel.

Anyone see any issues with this idea?

Anyone know where I could find a stainless Savage .280ai barrel?

Thanks!
