BRP and BRP Adjacent Power Systems?

I am working on a campaign that I'll hopefully get to run in the next few months. It's primarily non-Glorantha Runequest. I'm looking for a magic system to fill the void of Sorcery, but I'm not finding anything that quite fits what I want. So I've been looking through all the power systems for BRP that I know of. These are the ones I have found or have at least heard of. Are there any I have missed? This can include somebody's homebrew that's on the web or whatever. BRP Wizardry Sorcery

I use a few magic systems which I've cobbled together from other games but they suit my style of play and probably not yours (entirely). I play mostly a low-power magic world, so that will turn you off. However I do like strategic and long-term spell casting, and these are not in your list so that might interest you. 1. The Maelstrom magic system from a little game from the 80s. Freeform and based on probability. No pre-written spells, just desired effects and influencing the chance of them
