New Ideas for a music genre

I'm not one of those guys where you read a dating profile saying "I listen to anything (but [insert one to three music genres]). Maybe with a few exceptions, I listen to mostly underground/lyrical/hardcore hip hop/rap and heavy music (generally metal, but some hardcore punk and hardrock). That said, when was there a new genre of music created... that wasn't electronic/EDM music? I've been searching... barely, but been thinking of one for a while. That said, I write raps, but can't play instruments. Have a guitar for about 5 years, but too intimidating and frustrating, or learning wrong. However, when it comes to music, things usually seem to be too formulaic. Music seems to have "rules," even in genres that are criticized for being too out there, like extreme metal and such. What about "breaking the rules" on how to play music?

I've been wanting to experiment with a sound combining hip hop and metal, but not nu metal. Hell, no 6-string guitars at all. Instead, replace the guitar with keys (piano, organ, keytar, even a synthesizer). As far as the bass goes, I'm thinking like a rhythmic flow, but with a metal level of distortion. Think the nu metal guitar replaced by the bass itself, but maybe the higher pitch strings than the lower ones (no guitar). For drums, that a tough one. Trap beats... maybe, due to the speed it has compated to boom-bap rhythms, but still not trap. The cymbal plays on a constant pace, like a breakdown, but the kick drum plays with a hip hop rhythm, with the snare doing it's... snare timing. I guess here is a "chart" for how it would go, only it may be better if I could put this on a typewritter font to keep them aligned (I use LMMS for beats, but suck at it):
KICK = 0--00-0---0---0-0--00-0---0---0-
CRASH = 0---0---0---0---0---0---0---0---
SNARE = ----0-------0-------0-------0---
As for the vocals, I'm thinking like hardcore punk/extreme metal vocals, but with a rap flow. There are already good examples of this, with artists like Zack De La Rocha, Hopsin (both being hip hop examples), Tom Araya, Corey Taylor, Chad Gray, Max Cavalera, and even Jamey Jasta (being rock/metal examples). Shouted, growled, or screamed vocals with a bit of a "rap flow" or similar.

I don't know what this would sound like, but it's not supposed to sound like nu metal or anything, let alone be metal, but something completely different, but fear that could become what it would be related to. Been thinking of calling it thump (emphasis on bass and keys being kinda like instruments you press or hit) and trigg (like a trigger of two hardcore types of music, hardcore hip hop and heavy rock/metal), and just thought of an original name: Thrigg. Doesn't sound like anything already out there nor sounds like another word, I hope.

Looking at jazz, blues, funk, rock n' roll, and disco, they have their similarities, but aren't the same. This is what I'm trying to do, but with a lack of skill and money in playing and buying instruments, and being bad at doing hardcore shouts (growls may be too much...) aren't working for me, but hell, if I can't do it, maybe somebody else can. I know people may say "DUDE!!! You could have profited off of this yourself, just make it!" But since I can't, maybe, just maybe, somebody can experiment with this idea. If I can't be the creator, I'll be the customer, as I sometimes say.
