The current home jersey's are nice.
The away leave alot to be desired, I agree with the comments that the royal and navy on the same jersery looks bad.
Pussyfooting around copycating should be done, but not at the cost of ugly uni's.
Unfortunately, the superbow uni's were the same extremely similar to the giants at the time and they have since lost the stripes on the sleeve. A switch back to those would be alright, but the more up to date look sells better.
I would recommend a hybrid of the current style and the old school style the giants and lions wear. how exactly it would look, i dont know.
Using a solid gray pant could look cool. Also just go solid Navy with the helmet stripe around the shoulder and then limit the outlines on the numbers to just one color. Thats where I would start.
