In answer to your question, though I think I probably answered it in regard to someone else (or it may have been you) I have tinkered with trying to delete teams that are invisible but there must be something somewhere I haven't decoded to make it work.

In terms of file size I did make a batch of suggestions about how things can be optimised, and I have ideas about how the game log/box scores can be databased and generated on the fly (and I think my structure would be smaller than the associated text files), and also that for online leagues an incremental approach could be adopted for files.

Take for example a team in teams.dat that has got 20 years worth of batting history, pitching history, financials, etc...

In every sim those figures will never change but they'll get included in any update sent to GMs. The export part of the game only really needs to export the bits of the file that pertain to the current year and then the receiving game knows that it only needs to stick them in to the current year.

In players.dat one of the biggest sections is the At Bat Batting Stats. Once a game in a season has been played these records are fixed (until deletion at the start of the next pre-season) so they don't need to be sent back and forth for any future sim that season.
