Yeah, it wont be too hard to implement with a few global numerics.
But with the amount of content TSLRP works with, sometimes around the entire game, modifying globals to work differently can take a lot of work. Personally, not really willing or required to transfer all those over to another system.
For Handmaiden 4 females I probably just change it to a boolean instead, problem solved.
There is a lot more with the Hidden Complex than just numerics hitting the cap that makes it incompatible with TSLRCM. It was already deemed so before M4-78EP, which would make it fall way under the 1000. If it's to be compatible, a lot more needs to be done than converting the globals, other files will also need to be updated to reflect 1.8.2 rather than vanilla TSL.
Lastly, I doubt it. More to do with being a 8(?) year old game now. I'm pretty sure most didn't know about this, I certainly didn't. And considering this is the first I hear about it in those 8 or so years I suspect most others don't either...
