I don't se the purpose of making a new uniform. I don't know about your troops, but in ours the only time a uniform is worn is at meetings, on the ride to and from campouts, and at camporees. The rest of the time people wear basically what they'd wear at home...
There really are no problems with todays uniform. Sure, it'd be nice if the shorts were a little looser and there wasn't as much bunch in the crotch of the pants, but other than that it's fine...
