Left to its own devices, Scouting won't change or, if it does, it will be at a glacial pace. I'd suggest that you not just wait for BPL to take the lead in dragging Scouting into the present day. One way to look at your council's request to get involved with Scouting again is to consider it an opportunity to be an activist for updating the Scouting camping & backpacking philosophies.
Since they're asking you for help, stand firm and agree to do it only on your own terms.
I agreed to become a backpacking merit badge counselor on condition that we would not use the woefully outdated merit badge handbook. (The requirements are still valid, since they're general in nature, but using the information in the handbook is not only inconvenient but, in some cases, downright dangerous.) Instead, I gave all the boys copies of Harry Roberts' Basic Essentials of Backpacking (which also has some minor errors, but is overall a very practical, well-written 60 page primer on recreational backpacking.
The troop agreed to let me teach the kids a lighter, more efficient approach. While it's not ultralight, it is "verylight" using lighter versions of traditional gear (Clip Flashlights instead of Timberlines, Granite Gear packs instead of Kelty and Camp Trails, etc.) It's working out pretty good, and it helped break the traditional way of thinking. (The Scoutmaster, whose collection of cast-iron and canvas 60's-era "official" gear still looks brand new, even commented that "this sure is an easier way to camp.")
Get involved - but do it on your own terms, and be part of the change.
