Better. The timing is way better with a heavier influence at the tail end of the boil. However, magnum is a terrific bittering hop which isn't great at the end of the boil so I would use that at 60. Cascade on the other hand is terrific at the end of the boil so I would use it there. If you want to bitter with cascade I would still use it at the end and just dump the magnum then.

Go for it. I'm interested in hearing how the final beer turns out with this hop schedule. I worry that you're putting way too much super alpha bittering hops in for the whole boil, but just because I worry about it doesn't mean it won't turn out fine.

I recognize that you need to use 16 ounces of hops and that you have 6 magnum, 6 warrior, 2 cascade, and 2 chinook. It also sounds like you'll only be boiling about 3 gallons of the final wort. If I were limited by your constraints, this is how I would do the hop schedule:

60 minutes -
1 Magnum
1 Warrior

15 minutes -
1 Magnum
1 Warrior

10 minutes -
1 Magnum
1 Warrior

5 minutes -
2 Magnum

0 minutes -
1 Chinook
2 Warrior
1 Magnum

Dry Hop -
2 Cascade
1 Chinook
1 Warrior

I would also make sure to use the 2 pounds of dextrose to help dry out the beer so it's not too sweet. Keep an eye on fermentation temperatures and as the fermenting it finishing up start to bring the temp to the upper range of US05 to help promote a good full attenuation.

Most importantly, have fun and report back how the beer turns out.
