Yes, if you show all channels and then make your list, you can add the SD version of the channel. They remain in the list if you then switch to hide SD channels. I used to dupe TBS and Cartoon Network when they showed more stretch-o-vision but recently took them out. I only have FSOH, FSCIN, FSWIS, and FSOK SD only in my favorites lists just for grouping. I can be OCD with things and had it so that if I started at 628 NESN, I could page down by region by stategically adding a few alts here and there and not having the and SD and HD versions of those channels allows me to do that. I also used to have the SD version of my local MY channel in my favorites list because their HD audio was messed up. It was the same OTA and on TWC. They recently fixed that so i put it back to HD.
