I personally would find this inconvenient, as my entire Top Gear Library uses that format... To change it now would mean that I either A: have to redo the filenames of all the files in my library, or B: change the filename every time I download a new episode. Plus, IMHO, the current format is the most logical format...
Show name - [season/series and episode] - air date [video quality, uploader]
Makes perfect sense to me. Plus, I like having the original air date included in the filename, as it makes it easier for me to add them to my TG/TGUS/Fifth gear playlist, which plays all 3 shows by air date.
I personally don't agree with changing the format... This is something that should have been considered long, long ago, and I think it's too much of a headache to go changing it now.
