There has been some steady (but slow) progress on an open source firmware for a few popular printers, with one of the goals being to allow multiple file formats. I believe they're still targeting the Mono 4k and Saturn for their first release, but I haven't checked in on the project for awhile.
Have you looked at UVTools? There's a Nuget package you can import that lets you read / modify sliced files.
