I cannot see any sanity to this at all. There is an Ambassador membership and a fairly small pool of Royal Ambassadors
Anyone wanting better rooms can actually just book them up front and many hotels already offer discounted rates for bookings > 14 days in advance with advance purchase rates
Start adding a large pool of people with such benefits and can see very strict policies starting to be enforced by hotels on what they do provide rather than many being fairly generous in relation to what they offer
As far as a friends/family rate type thing, the friends and family rate already exists together with its restrictions
If wanting to pay less for hotels, there are plenty of other options
