A 1080i 59.94 10 bit RGB 4:4:4 QuickTime file size, is going to be what it is. If you want smaller file sizes, record/capture to a different setting, Down converting on ingest will make smaller SD files but you don’t want that I’m sure.
8 bit files will be smaller. Did you record in 10 bit? If not, don’t bother didging in 10 bit.
You could run all your files thru compressor and convert them to motion jpeg codec, this would greatly reduce the file size, but at a cost.
Just except it, 1080i 59.94 10 bit RGB 4:4:4 is going to be what it is.
