Now that I have your attention with the partially accurate title...
Here's the Beer

What I propose by this suggestion is really that the level cap will be removed, but beyond lvl 21 the HP will not increase, the skill points per level will be reduced to 1/Lv and only "Blueprint" perks can be taken every second level (3rd if skilled trait [Punishment]).
BluePrint Perks
Tesla Armour Discovery
Combat Armour Holo-Plans
Combat Armour Improvements (Need the CA Plans)[For CAMK2]
Brotherhood Secrets (Need CA Improvements)[For BA]
Ranger Secret Alloy Modification Holo-Plans (Need CA Improvements)[For NCR Ranger CA]{Just Hypothetical}
Etc...
(So, to be able to craft BA one has to achieve Lv 30 or 27)[Or we could place a certain level until you can craft it, like 33 or something like that]
In other words Tier 3 gear will be available to be "perked" so one can craft it, and with the future risk upping to get to the crafting areas it would make for some measures against alting. Can't elaborate much more really...
So, any feedbacks?
