Will These Front Calipers Work?

This is a guess. Everything about the 2nd Gen f-body setup is bigger. Larger spindle, larger diameter rotor, larger caliper, larger pads. I would say for a conservative guesstimate, at least 8-10lb difference between 2nd Gen F-body and a G-body per side.
besides your guess on the weight why would you think there is no advantage of a larger rotor, larger caliper and larger pads, also with it being a taller spindle it also helps with camber. One other thing is the F body spindles give about a 1/2" wider track adding stability to the car and it keeps the tire more in line with the wider rear I have on my GP
B-body Brakes come in 11" and 12". The 11" B-body brakes are 5 - 4 3/4", the 12" B-body Brakes are 5 - 5". The Spindles are different. To get 12" B-body brakes with 5 - 4 3/4" bolt patter you run Camaro 1LE brakes with the 12" B-body spindles. A B-body 11" spindle is basically a 2nd gen F-body spindle.
The B-body Brakes do stop the car. Tall Lower ball joints and a Howe adjustable center link do take out most of the bump steer when driving.

Other than weight and cost, there is not an advantage with a g-body front brake system.
For a street/strip car, in my opinion, I don't think spending money on different brakes is necessary unless you go to a full on drag race brake setup for weight savings. This money could be spend on other things that make your car go faster. For a stock setup, the g-body front brakes are the lightest system and they do the job at stopping your car at the strip on on the road. I would only upgrade the rubber brake lines to stainless steel braided lines and flush the brake system if my calipers were in good shape. For street/strip, I would pick a street pad that works best at colder temperatures and will not need a lot of heat to work optimally.
I believe the b-body brake setup is the best upgrade you can do for the money if you need larger brakes. I would not do this upgrade for a street/strip car because there is no advantage, in my opinion, of doing this swap for a car that goes to the drag strip and is driven normally on the street. Brakes do not make you go faster at the drag strip (only if they can be reduced in weight which costs money), they only stop you at the track, and the g-body brakes are more than adequate to do this at the track.

The reason I use the F body spindles is because they are tall spindles. I had no issues stopping the GP with G body breaks using the EBC pads. We raced G bodies on asphalt circle tracks on 1/4 mile, 1/3 mile and 1/2 mile tracks. We used F body spindles on all the 4 G bodies we built and sprung weight was very important along with the unsprung weight, especially the dynamic unsprung weight. The tall spindles helps us to make sure of the camber gain we got in corners and the tire temps told us how the suspension was working. If the F body spindles did not help with the handling of the G body we would have done something else. The results of finishing in the top 5 just about every night and bring home the checkered flag on more than one occasion told us we had the right recipe. All the cars ran the crate 602 so it's not the engine that counts, it how much you can keep the speed through the corners is what's important. You guys can talk about all theories you want, but you can't be beat experience.
Man, I am glad this discussion took off. Lots of great experience to draw from.
