HTML5 player on older Subsonic 4.6

[supra92]

Longtime Subsonic user/subscriber since 2006 -- always upgraded to the latest version each time one was released, up until v4.6. That's what I've used the past 10 years, because that was the perfect Subsonic to me.

Now, of course, Adobe has yanked support for Flash, and it's no longer usable in Chrome, Firefox, etc. Is there any straightforward way of replacing the Flash player in Subsonic 4.6 with an HTML5 player? I have tried the latest Subsonic, Airsonic, etc. along with Plex and other options... and absolutely nothing beats Subsonic 4.6 from a web UI standpoint. I would be eternally grateful to anyone who could provide direction/guidance on how to accomplish this!
