Pick Jacky and have him do a low hold on kicks. Nereus on FSD back then on Ultimate found this out by testing hold damage, so it should be obvious the entire cast universal WUK can do this, however he is the only character by far who has access to a downed state from a hold to perform WUKs (Sarah has her version in Tag only). In fact, he is the only character to have an unholdable WUK when the opponent chooses to get up (has to be timed only) but you can also enable a low WUK as well should the opponent choose to stay on the ground to tech them up.
Was doing a quick arcade run and apparently a low wake-up kick would count as a force tech... I'm guessing in the slim chance that both players floor each other, this can be used as a way to KO an opponent who strangely is not getting ul. Seems very rare although two Zacks and Brads in a mirror match might have a better chance of this occurring XD
....I'm sorry if this wasn't anything relevant, I just saw it and thought it was kind of neat to know that low wake up kicks had more situational usage.
