How can I fold Sorcery Points into Spell Points without over- or underpowering the sorcerer class?

Question

I'm working on a homebrew Sorcerer class and was thrilled to run across @user55434's and @Akixkisu's answers to How does the Variant: Spell Points system from the DMG affect game balance?: if the idea of the sorcerer is flexibility, then of course she should just use the Spell-Point variant but use her Spell Points for spells, Metamagic, and class features.

I'm having trouble figuring out how to make that work, though.

Of the two answers I mentioned, the former doesn't mention a mechanism. It seems clear, though, given the issues raised by the answer to What is the conversion rate for Sorcery Points to Spell Points?, that saying a Metamagic that costs 3 Sorcery Points under RAW now costs 3 Spell Points is likely to create a seriously overpowered character.

The latter of the answers I mentioned discusses converting Spell Points to Sorcery Points. I can imagine doing that, and then using the numbers from the Spell-Point-to-Spell-Slot conversion table (so 1 Sorcery Point costs 2 Spell Points, 2 Sorcery Points cost 3 Spell Points, etc.). But that raises other questions. How many extra Spell Points should sorcerers get to make up for the Sorcery Points that are being “taken away”? How many Sorcery Points can be created at any one time?

I'm interested in hearing from people who have played in a game with a Spell-Points-only version of the sorcerer. What mechanism did you use, did it keep the game more or less balanced, and did the person playing the sorcerer enjoy it?

Answer 1

Keep Spell Points and Sorcery Points separate.

In short, follow the RAW: when using the Spell Point optional rule, a Sorceror would get a number of Spell Points instead of Spell Slots, along with a number of Sorcery Points based on their normal Sorceror progression that they could use for metamagic and class features. These would be separate pools, though they could convert one into the other using the rules for converting Sorcery Points into Spell Slots, and then converting the Spell Slots into an appropriate number of Spell Points in accordance with the relevant tables.

Following this guidance, you should avoid altering the power level of the Sorceror relative to every other spellcasting class that is also using the Spell Points system.
