More "towers"?

I'm terribly sorry if this was already planned, implemented, or whatever of the sort which would make this suggestion embarrassing.

Currently, since I am an "oldie" returning after a year or so, a lot has changed and I've just defeated the first stage of the shadow tower, and my goodness you guys went away from the 'Ol golem and made some awesome bosses. What made me a bit disappointed is that there was only one tower from what I had seen so far in the "new" trove, and I would like to try and create a sort of symbolic dungeon for every biome. Currently I view the Shadow tower as one for the corrupted woods. If we added a tower for every biome that would be amazing, each one having they're own theme and unique bosses.

I thought maybe you could instead of making new altars for each tower, make a new model and rename the shadow tower altar to be more fitting. What I thought as a system was to first only have the current tower and once you defeated it one or two more towers would appear for that biome, making it so you don't instantly get access to all towers and instead have to work for it, effectively extending the end game which Trove has been working on notably due to reduces in loot.

Please ignore this if it has already been confirmed slash debunked, and I hope you have your own ideas about this that you can post below.
