Portal from the Void - Game Mode Concept

I was reading a post by Zeanix (https://boards.na.leagueoflegends.com/en/c/story-art/EEsy8B5u-will-there-ever-be-a-big-void-event ) and it gave me an idea for a cool Game Mode.

I will explain.

You have multiple void gates/portals all over the map (some in river and jungle with one on the top and bot of the map). Summoners rift 5v5 basic gameplay however you can go through the void gates/portals and it will take you to a different part of the map (this could be a set location or completely random). This would be a fast paced game mode because the surprise gank train from each team could always be rolling (with huge counter jungle play).

After each tower goes down you could have a portal appear on that tower for a set amount of time like 2 min (1 min for inner tower and 30 seconds for nexus towers) that would help with pushing, keeping it fast paced. The linked portal for the team that took the tower would then spawn in base in between the coinciding lane tower and nexus (used to come back in the fight if you died or return from tower to heal and head back into the fight).

Welp its just an idea but I think it would be awesome. Let me know what you think.
