Replacing videos on Commercial Disc?

[DarthMarino]

For the first time in my many years of collecting discs, a Blu-Ray has died on me. It is known to have disc rot/bronzing issues and has been out of print for some time. I won't bother rebuying it since this will likely happen again. I luckily found a torrent of the full disc but Russian dubs were put in. I would like to keep everything the same (menus, etc), but make 2 changes:

1. I would like to do a simple remux to remove the Russian audio or make the 5.1 English audio the first track. If I make this simple change, can I just burn the disc as is and expect it to work properly?

2. There are some short film bonus features in SD on the disc. They've since released these in HD online. I would like to replace the m2ts files with HD m2ts that I've made, again with a simple remux. The files will no doubt be larger but should be roughly the same length. Again, can I substitute m2ts files like this and expect the disc to work properly?

I know I can make my own menus and all that, but I'd rather keep everything as it was on the real disc and not spend too much time on it. The torrent disc is about 31 GB so there's plenty of room left for any increase in file size. I just don't know how Blu-Ray structures work enough to know how the files are read.

Discussing warez releases = big no no (read the forum rules)

Thank you for the fast reply. Sorry, I thought this would be considered fair use since I own the original disc.
