Framerate conversion question

Hello all. I'm new to this forum and fairly new to video editing. Here's my quandry in as few words as possible.

I mainly record audio, and in many situations I find myself needing to compile videos from multiple sources and sync all of them to one single audio file. It's clear how to deal with situations where the audio falls basically right in the middle of a frame, hence creating a very obvious lack of sync between A and V.  Just adjust the beginning of the audio to match the video. I've done it million times and it's easy.  But in a situation where one of the videos I get is synced up well and others aren't, adjusting the audio (music) is not an option on a per-clip basis unless you want horrible skips and surges in the music. Obvioulsy unacceptable.

So, I think I understand that it's not possible to move video by less than one frame. But is it possible, even in a utility outside of Premiere, to convert to double the frame rate, trim one frame from the beginning of the clip, and convert back to a Premiere Elements-supported frame rate, hence adjusting the beginning by half a frame at the slower framerate?

Clearly the professional way to do this is to have cameras that are all synced to one another, but that's not really possible when you have one person in Italy, and another in Baltimore, and others in Florida, and yada yada...we all know how that goes, especially lately.  Unless the audio session is synced with SMPTE or whatever (is SMPTE even a thing, anymore?) and each musician uses the same stripe to clock their cameras...technology that the vast majority of folks don't have.

Any advice would be greatly appreciated!
