For sure.
I often let myself get carried away with modifying this game, sometimes to the point where it is pretty much a completely different game. The main feature of D&D when it comes to finding people to RP with is name-recognition. It is much easier to recruit people to "play D&D" than it is to convince people to play almost anything else, especially something they don't already know. It is a fine balancing act, one that I sometimes go too far with and have to scale back my enthusiasm.
Well, either that or just treat it like a creative endeavor for the fun of it and don't be attached to playing it. I mean, it's really fun to mess with this stuff.
I've put a LOT of work into our game house rules and West Marches setup, in Slack and Google Docs, and it's 90% for us three DMs, and players won't ever really read it - just listen when we talk about it.
