Well, let's go with realism and say that Lightning do not bottom out next year and will be a playoff team. If we knew that they will not miss the playoff next year, then we would want them to bottom out this year. Lose in the 1st round. That gives us the 20th-23rd overall pick (assuming they win their division) for this year. Now, next year, still under the assumption they will make the playoffs, we either want them to win the cup (31st pick) or go out in the 1st round (47th-54th pick, based on whether or not they won their division). Them losing in the cup finals would give us the 61st pick.
A betting man would say they are making the playoffs next year. A betting man would also take the field over a single team, almost regardless of the team.
So I am vying for 1st round exist this year, and 1st round exit next year - because I see them as likely to not bottom out and miss the playoffs next year, but I also see it as less then 50% likely that they win the cup in either year.
But yes, the hypothetical where they win it all this year and then they all get kicked out of the league for doping next year and get the 1st overall next year is the best case scenario.
