I've got a wheel that I want to switch the hub out on, but the replacement hub is significantly higher flange. I really don't want to have to go buy some new spokes. If I make a snowflake-type wheel, I can use the current spokes. I've done it once before and it seemed fine once sufficiently tightened up.

Any compelling reasons why I shouldn't do this? Current wheel is a 26" deep v with a BMX hub, laced 3l3t.
