I'm a bit iffy on the F3 mixups because of how telegraphed the animation is and that fuzzying F3 or F3xxMB teleport shenanigans may not be too difficult (teleport has 16 startup and the second hit of F3 seems to be noticeably less than that, not counting the extra frames you have to add once you do something after MB teleport).
The 112B3 / 112 MB teleport mixup looks quite good (though MB DB2 may be better as REO as a reply to my comment) as does 3B3 or 3xxMB Teleport, those two I'm quite sold on. MB orb shenanigans also look quite nice, especially if you factor in that 112B3 will probably combo in the corner. 112, B1 may also be a mixup in the same sense that 21D3 and 21xxF3 bounce cancel is a mixup, which means you could pop in a B13 in the corner to safely launch them into the orb.
