Wick 4AL (large shank) or 4AM (euro shank) would be the classic choices for those instruments. Schilke 51D (or a clone) is a little smaller in diameter and a little deeper, and is the more standard american (bowman) school of playing choice. You could also look at the DEG BB1 which is a lot like the 51D. You could also look at one of the Wick SM or SM Ultra series in the player's choice of size.
If you've taken a brass methods class, or two (Or know someone who has) you'll realize that at best in these course you spend 6 weeks learning each instrument or in the worst of cases you spend 3 weeks.
In that time frame, your claim to "are all way too small" is frivolous at best. I doubt that students will have enough precision and control to reap the benefits that a larger mouthpiece might offer.
Your recommendations are not bad, but I doubt they are the most practical in this thread. One of the added benefits of buying a Bach 5g is that the teacher will have a clear idea of what an upgrade from the generic 6 1/2AL might be if one of his students decides to switch later on. A 5G is a very "play it safe" type of mouthpiece and I have seen it used on many different makes of horns without any issues.
For the record, I played an Imperial from three years and own a 3 valve compensator. I have used a Willson TA1 (Similar to a 5G) without any problems..
