Well not to rain on anybody's high hopes, the chances of Universal listening to fans who want to see more LBT, whether it be TV or movies, is really slim to none. It has already been established that LBT was not making much money for Universal considering the seemingly decrease in the quality of the movie sequels, and while the TV series did provide potential to be a boost, it probably didn't seem like it would go that far. The same thing happened to Terminator Sarah Connor Chronicles on FOX. Despite great reviews from fans, it didn't bring in much profit so it was cancelled after a very short first season. Luckily, it was renewed for a second season, but mainly because Terminator Salvation was coming out later.
In Universal's mind, renewing LBT probably would not be a worthwhile move. While it would certainly make fans very happy, it would require money to continue it, and if it does not bring in a profit then it's just Deja Vu. I think in order to really have a chance of renewing LBT in the future would require possibly an attorney or some sort, also you would have to come up with a VERY EXTREMELY convincing argument. Shows like Courage the Cowardly Dog, Teen Titans, and Danny Phantom were highly successful shows in there time, so it probably made much more sense for their respective producers to put them back on the air, even if they are just reruns.
Nevertheless, I applaud you for at least stepping up and doing something about it. So many people want something done but do not have the courage to do it, so it is refreshing to see that somebody is not afraid of being rejected to voice their opinion. Perhaps if more people, and I mean A WHOLE LOT MORE, were to take the same action as you then maybe there would be a chance of seeing LBT again in the future.
Anything is possible, but only if people put the effort into it.
