This was the whole idea I had behind nhl94hockey.com but no one wanted it because "I don't have time for exhibition games." I had about 40 or so people signed up at any given time, but it ended up being largely me and my buddy Kero5hin doing all the gaming. Admittedly, my playtime has dropped in the last couple years, but I still update the site with minor bug fixes and stuff. Actually doing a couple bugfixes at the moment!
Hopefully it works out for you where it didn't for me. I honestly think the largest problem I had was no instant name recognition in this community. It's very insular and cliquey.
EDIT: btw my name on https://nhl94hockey.com is halfMANhalfDONUT and Kero5hin is HeatRash (in case any of you want to play us at any point)
