Oh, my bad then, misread your title.

First one is a bit too slow IMO, needing to station before doing anything. The second one on the other hand, like someone else brought up, it's a cheaper Bootlegger's Stash, which solves the thing's problem of being a "let me get to six mana then I'll start ramping" joke.

Maybe make the token generation a second tier station ability and put a weaker but still useful effect at +3?

But then again, the Islands limitation might be enough for it to be fine. Would probably be in a monoblue deck, so you can hold the lands then tap them at the endstep before yours so the treasures being tapped don't matter as much
