Ideas for a Shen rework

Shen has been for a long time one of my preferred tanks and I've always found him fun to play, however recently he has fallen out of the meta due to the fact that many ranged champions have been going to the top lane and he gets zoned out easily in many cases. In the case Shen needed a rework, here are just the way I think his abilities should be designed to make his tanky ninja playstyle his main role as well as making fighter Shen a viable build path.

(Passive) Ki Strike - Shen's next auto attack deals (3xShen's level) + (8% bonus AD) + (6% maximum health) magic damage and restores 20 energy (Second Passive?) - All targets marked with (x) are slowed by 8% and receive extra magic damage on auto attack equal to 6% of Shen's bonus health.

(Q, 65 energy) Vorpal Strike - Shen's next auto attack within the next 4 seconds gains 120 range, deals 60/100/140/180/220 + (25% total AD) magic damage and marks the targeted enemy with (x) for 5 seconds.

(W, 50 energy) - For the next 1.5 seconds, Shen blocks any projectile/auto attack towards him and slashes around himself (140 range), dealing 30/40/50/60/80 + (60% AP) + (7% bonus health) magic damage. If an enemy is hurt by Shen's slash, they are slowed by 30% for 1.5 seconds and Shen restores 10 energy.

(E, 100 energy, 550 range) - Shen dashes through instantaneously in a mechanic somewhat similar to Ezreal's Arcane Shift, dealing 50/70/100/130/160 (60% AP) magic damage to enemy champions he warped through and taunting them for 1.5 seconds. Taunted enemies deal half damage to Shen. Shen gains 40 energy for each enemy champion he contacts.

(Ult, no energy cost) - There's nothing I'd really change to Shen's ult, but perhaps a small 200 range stun for 2 seconds if the ally he ulted dies before Shen teleports.

Please tell me any changes you think are necessary to make Shen's kit more viable in the current meta :D I'd love to be able to play him in his prime again.
