The 24 and 1.4 TC make a very high quality 34mm, there is no way on earth Canon are going to make a TS-E 35mm because they know that even though it is not officially supported it works perfectly well.
Yes the 1.4 TC works with all TS-E lenses, however, I would not call the 24 TS-E L II + 1.4 TC combination a very high quality lens. I have all 4 current TS-E lenses and I would say 75% of my pictures are made with them for my work, in interior and architecture. Although they are all very good lenses, they are not without flaws.
The 17mm is very bad at handling flares, the 24mm is better a flare but shows quite a bit of blue / yellow fringing, the 45mm is quite sharp but has brutal cyan / red fringing (plus purple when you shift), and has a strong field curvature, finally the 90mm is the one that still has the most balanced behaviour, no fringing, flat field and still very good sharpness from corner to corner; I wish sometimes it could have a little bit more crispness, like the 135mm f2 (@ f5.6/8).
I do use them (on a 5DSr) with the TC 1.4 III, when I have to (except for the 17mm), but only when I have no choice. The 24mm + TC 1.4 is the combination that suffers the most, with noticeably softer borders and the blue/yellow fringing of the 24 TS-E II is even more apparent.
Strangely there is less IQ loss on the 45mm (the fringing is so bad on that lens, the 1.4 doesn't change much) and almost no penalty on the 90mm (aside from a very slight sharpness loss).
I would love Canon to replace the 45mm with a 35-40mm AND a 55-60mm
