chairlift track works for coaster track but is there anyway to make it invisible so it doesn't look weird under smaller track pieces like monorail track?

Full tile flowers or garden clocks work. Build them then bury them with Codex.

Build chairlift then make it into crooked house track?

Tried crooked house already but it didn't block the supports. I'll try what liampie said

Lower the land 1 unit, place a full tile garden or clock.  Then raise the land back up with 4cars MOM (it will be 2 units in 4cars).

You can also bury and unbury that track piece (colour it, then use Dragons5's feature on this). It's a bit of a hassle though once you need to make changes to that tile.
