Potential Endgame Difficulty Solution - Apply Waystones to Pinnacle Boss Fights?

A potential solution for both sides of PoE2's community would be to allow all forms of content to scale based on area level, both up and down. This could be solved by allowing the player to use a Waystone when entering a Pinnacle Bosses' Fight. For Example: When the player finishes grind out the 50 Breach Splinters needed to challenge Xesht, and go to use the Realmgate, there would be the menu to place the 50 Splinters, with the addition of a small space below of next to the Splinter Input space where that player can insert a Waystone (like the relatively new Tablet System). This could determine *NOT ONLY* the level of the area/encounter, thus helping reduce the difficulty for Casual Players who may just want to experience the content available in the game. BUT could also work to help Veteran Players even further boost the challenge/rewards available upon success. Thus, bringing positives for both the Casual and Veteran sides of the community.
