Chains aren't that expensive, so no reason I can think of not to do this..
Sound like a decent approach?
No, it's not a sensible approach because there's no reason to. The chain sized for the larger cassette can always be used with the smaller one, since both cassettes likely use a similar sized smallest sprocket. So, once you have the chain long enough for the larger cassette there's no reason to switch back.
As to what others use, it's not relevant because they may have longer or shorter chainstays. Here's some
good advice about dangers of basing your bike on what others do.
