One of the homebrews I am making is a Pokemon homebrew, but the source material uses a 1-100 Level System. As you know, 5e stops leveling at 20. Of course, the obvious solution is to just divide all level-related things from Pokemon by 5 to make the two fit, rounding when necessary, but this creates some issues. Of course, I don't want to make 5e adapt the 1-100 system, either. If I did, I'd be bound to break the Bounded Accuracy of the game. As a DM, house-ruling and minor aspects of home-brewing is pretty basic stuff, but this seems to be more difficult since the choice would have a wider influence than making a pack of Lesser Werewolves or allowing a non-specific Wisdom (Perception) check as an Interaction.
Would my proposed method of making a L100 and 5e's L20 systems fit work optimally or would it cause me serious problems?
##Overview of Mechanics##
The idea I am toying with is creating a sub-level [Leveling System] exclusively for Pokemon, thus still allowing them to go to Level 100 (following their normal XP/Leveling system) and having everything else cap at 20 (using 5e's standard XP/Leveling system), while still confining a Pokemon's stat growth to something similar to the 5e system as if their Levels were [Pokemon Level]/5, to maintain balance. I don't know if this would work or if it would break the system. I've been looking at this too long and need a fresh set of eyes to tell me if this idea is functional or if I need to scrap it.
My intended goals for this change are that it 1) functions, 2) has minimal impact on other aspects of 5e's system, and 3) prevents a Level 5 Pokemon from being a murder machine capable of killing off a Level 1 PC without the system/DM having to enforce an exclusively Pokemon vs. Pokemon battle system that must be strictly adhered to (I want the idea of players vs. Pokemon to be a possible plot that I or others could play around with). These three aspects seem to be mandatory to get a conversion/assimilation to work.
The idea is to make Pokemon be creatures within the world, much like familiars, animals, and monsters. For a "Mystery Dungeon" campaign, where players are Pokemon, I would probably create a different module seeing as there are many stark differences between the two Pokemon systems. This is so you better understand what it is I am trying to do.
